National Radiologic Technology Week: Nov. 8-14, 2009
By Rachel Silveria and Stanford Imaging Services
During National Radiologic Technology Week (NRTW), an annual recognition established by the American Society of Radiologic Technologists (ASRT), we celebrate the great advances in radiologic technologies that have been made since the discovery of the X-ray on November 8, 1895.
The week of November 8-14th, we proudly celebrate all employees of Stanford's world-renowned Department of Radiology for continually providing outstanding care. Offering the best diagnostic imaging services and expertise while utilizing state-of-the-art technology, this Department never fails to demonstrate extraordinary teamwork by all its dedicated medical professionals. For more than one-hundred years, Stanford Radiology has made a difference in the lives of patients and their families, while continuing to . . .
make important contributions to medical and surgical advances. This hardworking Department, in this ever-growing Stanford community, continues to lead imaging-based research, patient care, and education. This year in particular, the Stanford Radiology Department has pioneered transformations in several areas. These significant advances, along with our teamwork and excellence in patient care, make our Department unique among radiologic service providers and serve as an inspiration to our patients.
Furthering our clinical imaging enterprise, we unveiled two new outpatient centers this year: Stanford Medicine Imaging Center in Palo Alto and Stanford Medicine Outpatient Center in Redwood City. Focused on patient comfort, both of our Centers have been designed to ease the tensions associated with health problems through innovative approaches to reduce anxiety such as promoting a calming environment; utilizing beautiful architecture; and employing a patient-centric approach to healthcare delivery. With the added imaging capacity of both Centers, we have accelerated our delivery of outpatient care, while providing imaging services with the most advanced technology available. By constantly innovating, we have placed ourselves in a continual state of technological advancement.
Additionally, we have completely rebuilt our Nuclear Medicine Clinic on the 2nd floor of Stanford Hospital and Clinics (SHC). After years of planning, the anticipated opening of the Clinic is July 2010. In addition to two new state-of-the-art PET/CT 64 slice systems, the design also includes a Radiochemistry Lab and a Health Physics Workshop. The work flow of patients will dramatically improve with the centrally located design and features.

Oldest Person Scanned at Stanford by Dr. Fahrig

(Images courtesy of Mark Riesenberger)
On August 20th, Rebecca Fahrig, PhD, directed the CT scanning of a 2,500-year-old mummy of the Egyptian Priest Iret-net Hor-irw. The high resolution CT scans were taken of the mummy in the AxiomLab and will be used . . .
to construct three-dimensional images of his skeleton to learn more about the mummy's life and death.

To acquire more information about the mummy's amulets, a second scanning procedure was completed at Stanford Medicine Imaging Center, Palo Alto, (SMIC) with a dual-energy CT scanner that differentiates between different materials. Through these scans, scientists hope to learn more about the substances used in the mummification process as well as in the composition of the amulets.

The mummy has been a resident of the Fine Arts Museums of San Francisco since 1917 and will be part of an upcoming show at the Legion of Honor Museum in an exhibition entitled, "Very Postmortem: Mummies and Medicine," which opens on Oct. 31, 2009. This exhibition is organized by the Fine Arts Museums of San Francisco with the cooperation of the Akhmim Mummy Studies Consortium, Stanford Radiology, and Stanford Medicine Imaging Center. Additional project assistance has been provided by the Stanford Division of Anatomy, eHuman Inc., and Fovia Inc. To read more about the mummy, please access "The Mummy Speaks: Detailed Scans at Stanford Help Reveal the Secrets of an Ancient Egyptian Priest" and "Mummy to Be Scanned at Stanford at Aug. 20."

This is Dr. Fahrig's second time scanning a mummy. In 2005, she led the team who scanned a 2,000-year-old mummy of a four- or five-year old girl (nicknamed Sherit, or "little one") from the Rosicrucian Egyptian Museum in San Jose.

Research by Dr. Wu and Colleagues Induces Fat Cells to Become iPS Cells

In a recently published paper, "Feeder-Free Derivation of Induced Pluripotent Stem Cells from Adult Human Adipose Stem Cells," senior author Joseph Wu, MD, PhD, assistant professor of medicine (cardiology) and radiology, and his colleagues describe how they reprogrammed fat cells (collected from adults undergoing liposuction) to become pluripotent stem (iPS) cells for use in tissue regeneration and disease research. According to Dr. Wu, "Fibroblasts, or skin cells, must be grown in the lab for three weeks or more before they can be reprogrammed. But these stem cells from fat are ready to go right away"(from "'Liposuction Leftovers' Easily Converted to iPS Cells, Study Shows" by Krista Conger http://med.stanford.edu/ism/2009/september/fat-cells.html or Download file.

Medical Students Need Earlier Exposure to Radiology According to Drs. Desser and Hovsepian

Although radiology still remains among the top 10 specialty choices, it has fallen from fifth to ninth, according to the National Residency Matching Program. In "Early Radiology Exposure Could Lure Medical Students to Specialty" from the August 2009 RSNA News, Terry Desser, MD, professor of radiology and residency program director, and David Hovsepian, MD, professor of radiology as well as chief quality and safety officer, describe the causes of decreasing interest in radiology while offering solutions.
According to Dr. Hovsepian, the diminished appeal of radiology as a career choice among medical students is due in part to "students' misperceptions about what radiologists actually do and the central role that we often play in patient care." One solution is to expose medical students early on to radiology, as Dr. Desser describes: "We need to be the ones teaching them anatomy and about imaging and manifestations of pathophysiology on imaging early on in their training, so they recognize what we do and what we contribute."

By Mike Moseley, PhD

(photo courtesy of Mark Riesenberger)
From August 3rd-7th, Stanford Radiology held its fourth annual Japanese Technologist Summer Training Program, a joint educational program in partnership with the Japanese Society of Radiological Technology (JSRT). As in previous years, we had 24 JSRT participants visit for the week, with technical lectures in the morning; tours and workshops in the afternoon; and social activities such as Giants' baseball, a tour of SMIC, shopping, and biking. For the brave of the bunch, Dr. Deb Ikeda once again led a dawn charge up to the Stanford Dish. The lectures were well received (many thanks to everyone who participated!). The highlight of the week was the reception at the new Stanford Medicine Imaging Center, Palo Alto, which gave the JSRT members an opportunity to meet and speak with many of our technologists. The Summer Training Program is a great way to introduce ourselves to the international radiology community, while building strong collaborations and more efficient practices in radiology worldwide. Many thanks again to our speakers and to everyone who spent so much time and effort to make this an ongoing success.

Veronica Cox, MD
Sarah Garaas, MD
Theodore Jerdee, MD
Tim Joseph, MD
Marnie Kremer, MD
Andreas Loening, MD, PhD
Nicholas Telischak, MD, MS
Jonathan Williams, MD

Ed was born in Taiwan and grew up in San Diego. He received his undergraduate degree from Harvard and then entered the Stanford MD/PhD program. After graduating, he spent a year completing a general surgery internship before starting in radiology. Ed likes to build things and loves the thrill of making something new and useful. Some of his recent projects include developing an algorithm for reducing metal streak artifacts in CT scans and creating a method for designing custom binding proteins. At Stanford, he plans to pursue interventional radiology and develop new medical devices.

Veronica is a lifetime Californian, who hails from the backwoods of rural Mendocino County. She grew up playing outside in the redwood forests and cooking-up amateur science fair projects in her backyard. Her "research" of "mudslides" brought home many prizes from the California State Science Fair, where she was also named "Most Promising Future Scientist." Veronica is very close to her three sisters, all of whom have also attended Stanford University at one time or another. Prior to entering the Radiology Residency Program at Stanford, she attended the University of California, Berkeley, as an undergraduate, followed by medical school at the University of California, San Diego. In her spare time, Veronica enjoys painting, listening to classic rock, and spending time with her new niece.

Tim Joseph is a true Californian. He attended the University of California, Los Angeles, for his BS, and then ventured northward where he attained his MD degree at the University of California, San Francisco. He returned to his hometown of San Diego to complete his internship, and made the return trip back to Stanford to complete his radiology residency. Tim is an avid sports fan (Lakers!), and traveler; he also LOVES eating all kinds of foods.

Marnie grew up in Fargo, North Dakota, and stayed in the Midwest to attain her bachelor of science degree in nutritional science from the University of Minnesota, Minneapolis. She went on to complete her medical degree at the University of Maryland School of Medicine in Baltimore, Maryland, where she also received her Certificate in Medical Sonography. This past year, she returned to Fargo, North Dakota, for her internship at the University of North Dakota. Marnie enjoys camping, hiking, running, volleyball, and travel.

Andy Loening (sounds like "Learning') grew up in Iowa City, and then headed to Boston to study electrical engineering at the Massachusetts Institute of Technology (MIT). After completing his undergraduate degree, he decided to check out the west coast, earning his MD/PhD here at Stanford. Continuing his slow westward migration, Andy finished his transitional internship at the University of Hawaii. He enjoys backpacking, guitar, fermented grain products, indie rock, and what he calls "dorking out" on his computer. Andy has also recently taken up surfing.

Nick grew up in the Bay Area but left for New England to study mechanical engineering at Tufts University. He attended Dartmouth Medical School where he met his wife, Kristen. Having tasted life at Stanford while pursuing a master's degree in bioengineering, Nick has returned for his radiology residency. According to Nick, he "dragged his wife, a lifelong New Englander, kicking and screaming" to San Francisco where she is a surgical intern at the University of California, San Francisco. When he is not in a dark room, Nick is bicycling, running, swimming, or trying to find the perfect margarita.

CCNE Nano-Bio Seminar Series Presents Donald E. Ingber, MD, PhD, "From Biological Design Principles to Bioinspired Nanotechnologies": Tuesday, April 21st; Seminar & Discussion from 4:30-5:30 PM; Reception from 5:30-6:00 PM; in the Clark Auditorium, S001, Clark Building at Stanford University.
Donald E. Ingber, MD, PhD
Director, Wyss Institute for Biologically Inspired Engineering
Judah Folkman Professor of Vascular Biology, Harvard Medical School and Children's Hospital
Professor of Bioengineering, Harvard School of Engineering & Applied Sciences
Abstract:
The burgeoning field of Nanotechnology offers exciting new approaches to attack fundamental questions in biology, create smart medical devices, and positively impact human health. Creation of biologically-inspired nanotechnologies also could revolutionize how materials are designed and manufactured for industrial, aerospace, and military applications. But the fields are constrained by a lack of understanding of how living cells and tissues are constructed so that they exhibit their incredible organic properties, including their ability to change shape, move, grow, and self-heal. These are properties we strive to mimic, but we cannot yet build manmade materials that exhibit these features, or develop devices to selectively control these behaviors. To accomplish this, we must . . .
uncover the underlying design principles that govern how cells and tissues form and function as hierarchical assemblies of nanometer scale components. In this lecture, I will review work from my laboratory and others, which has begun to reveal these design principles that permit self-assembly of 3D structures with great robustness, mechanical strength, and biochemical efficiency, even though they are composed of many thousands of flexible molecular scale components. We also are beginning to understand that biological materials are simultaneously "structure and catalyst": the molecular lattices that form the frameworks of our cells and tissues combine mechanical functions and solid-phase biochemical processing activities. In the course of the lecture, I also will describe how recently developed nanotechnologies have been used to create model systems for biological studies, and how they have led to new approaches to interface living cells with microchips, control mammalian cell and tissue development, and probe the process of mechanotransduction--how cells sense mechanical forces and convert them into biochemical responses. Finally, the more fundamental question of how nanoscale structural networks impact information processing (signal transduction) networks to control cellular "decision-making" also will be explored. Understanding of these design principles that govern biological organization is critical for any nanotechnologist who wants to harness the power of biology.

Stanford Radiology Welcomes Associate Chair for Education Michael Federle, MD

As our new associate chair for education, Michael Federle, MD, is transforming our educational programs at all levels, from medical students to practicing radiologists, by channeling the excellent technical and personal resources in our Department and on campus.
Since he arrived at Stanford this fall, he has been excited about the outpouring of support from faculty: "There are so many faculty members in our Department who are already integrating new teaching methods into the classroom and who are eager to play an important role in transforming education. One of the enticements for coming here was the opportunity to work with such bright and supportive colleagues." Dr. Federle has already initiated weekly teaching sessions with the body imaging fellows, and he will be taking an active role in our Continuing Medical Education (CME) Program. He is also working to ensure that there is dedicated space for radiology as part of the Immersive & Simulation-Based Learning Center at Stanford's Li Ka Shing Center for Learning and Knowledge.
Medical student education is one area in which Dr. Federle is also making a significant impact:
"I really think that Stanford medical students are not getting as much exposure to radiology as they should, and I want radiology to be part of their curriculum from day one and to play an integral role throughout all four years of their medical education." Towards this end, Dr. Federle has met with the Medical Student Curriculum Committee and with faculty from departments such as Anatomy to discuss improving and updating medical student education. As a result, Dr. Federle will be teaching part of the Anatomy course and integrating different teaching methods into the classroom, such as virtual dissections and 3D modeling. Overcoming the pervasive campus culture weighted towards new research and technological developments will be another challenge he will face in his new role as associate chair: "I have to work to assure that the clinical and educational parts of our mission are given their due time and resources to keep everything in balance."
Dr. Federle brings a wealth of expertise to our Department and its mission of improving health through excellence in image-based patient care, research, and education. He completed his undergraduate degree in biology at Marquette University in Milwaukee, Wisconsin, and went on to graduate from medical school at Georgetown University in Washington, D.C. After finishing his internship in internal medicine at the University of Cincinnati Hospital in Ohio, he decided that radiology was more interesting. He applied to and was accepted at the radiology residency program of the University of Cincinnati.
At the completion of his residency, Dr. Federle began teaching at the University of California, San Francisco, (UCSF) as a clinical instructor and then as a professor. As a clinical instructor, Dr. Federle had the opportunity to interact with many of his current Stanford colleagues such as Drs. Barth, Glazer, Herfkens, Jeffrey, and Van Dalsem. During his 10 years at UCSF, he served in a variety of prominent positions including chief of radiology; vice chair of radiology; section chief of CT body scanning and GI radiology; and chief of the medical staff. Prior to coming to our Department, he was the director of abdominal imaging for 16 of his 19 years at the University of Pittsburgh, where he also served as the chair of radiology as well as the chief of quality process and improvement.
Dr. Federle's interest in teaching began when he was an undergraduate: "I really enjoy finding new knowledge and transmitting it to others. It doesn't matter what the content is. So I studied biology as well as English and philosophy as an undergraduate; I thought I would end up teaching English. I eventually decided on medicine as a career even though I had no role models in the field because I come from a long line of farmers from southern Indiana." Throughout his career, his teaching duties have spanned the spectrum from teaching beginning medical students to teaching the most sophisticated subspecialty radiologists, and he has enjoyed the unique challenges of educating such a variety of audiences.
His numerous awards attest to his teaching talents. Dr. Federle has been awarded Teacher of the Year multiple times throughout his career. In 2007, the residents at the University of Pittsburgh created an award in his honor, the Michael P. Federle Mentorship Award. The residents developed this award to recognize Dr. Federle not only for his remarkable teaching but also for his service as a role model and mentor to future radiologists. In addition to his teaching, Dr. Federle's research accomplishments include 238 peer-reviewed journal articles and 17 books.
Dr. Federle is also a co-founder of Amirsys, which is a company that produces radiology textbooks to provide decision support to radiologists and to guide them in making diagnoses. He established the company along with Rick Harnsberger, MD, and Anne Osbourn, MD, neuroradiologists from the Radiology Department at the University of Utah, Salt Lake City. Each series that Amirsys publishes is based on the experiences of authors from around the country: "Our series of textbooks cover the entire spectrum of every specialty in radiology, and each have become the bestsellers in their field. Our online decision-support product, STATdx, is now used in several thousand radiology departments across the country including the great majority of training programs." Dr. Federle and his colleagues have just finished a new Expert Differential Diagnosis Series, which will be coming out at the 2008 Annual Conference of the Radiological Society of North America (RSNA). His contribution will be a section on the abdomen: "Writing for Amirsys is both a vocation and avocation; I really, really enjoy the whole process from gathering interesting cases to writing them up. I can lose myself for hours doing that."
After 19 years, Dr. Federle is excited to be back in the Bay Area and at Stanford: "I greatly admire my colleagues in Radiology. This is a satisfying and stimulating environment." Although he has been away from Stanford for many years, Dr. Federle's older son, Andrew, attended Stanford as an undergraduate. Andrew and his wife now live in Toronto, where he is an Episcopal priest. Dr. Federle's younger son, Tim, has performed on Broadway in New York, where he was part of the original cast of "The Little Mermaid." He is currently the choreographer and associate director for a new Broadway play, "The Prairie," which is based on the book series by Laura Ingalls Wilder.
When he's not in his office, you will probably find Dr. Federle on the Stanford golf course. At his golf course in Pittsburgh, he made a hole in one at the 15th hole from 165 yards away. He hopes to improve his shot at Stanford.

The Radiology Interest Group at Stanford (RIGS) "Meet and Greet" will include a panel discussion, a light dinner, and informal socializing with the faculty. Please bring your questions about radiology and life as a radiologist. Faculty from both diagnostic and interventional radiology at Stanford as well as residents and fellows will be present. Please RSVP to Bhargav Raman (ramanb@stanford.edu).
RIGS supports "interest in the field of radiology and provides advice to those who wish to pursue radiology as a career. RIGS holds events to provide medical students a better idea of what radiology is and what the various imaging specialties are, to guide those applying to residencies in this field, and to encourage women and minorities to consider a career in radiology; these events also allow medical students the opportunity to meet radiology physicians and residents. In addition, RIGS is a resource for those interested in research opportunities in the field of radiology" (from the RIGS Web site at http://rigs.stanford.edu/). Please contact Harpreet Dhatt (harpsd@gmail.com) for more information.

Dr. Basu Completes the 2008 J.T. Rutherford Government Relations Fellowship

(From left to right: Congressional Representative Bono, Dr. Basu, and Congressional Representative Mack)
This past summer, Chief Resident Pat Auveek Basu, MD, MBA, spent one week meeting with congressional members (please see a few of their photos below) as well as representatives of federal regulatory agencies in Washington D.C. as a Fellow in the J.T. Rutherford Government Relations Fellowship from the American College of Radiology (ACR). This fellowship exposed him to state and federal legislative and regulatory processes that directly affect the future of radiology. Dr. Basu described his fellowship as "a unique educational experience, an enriching professional opportunity, and a very productive endeavor." He summarized his experience as follows:
"Despite interning in Congress and working on a senate campaign, this was the deepest I have been immersed in the politics of the nation's Capitol. I met with lobbyists about issues we face in our practice; briefed an investment firm on my economic outlook for the industry; and attended seminars on policy and legal matters in radiology. However, the highlight was meeting with close to a dozen congressional representatives and senators to discuss matters pertaining to healthcare policy and economics. The discussion revolved around the recent passing of H.R. 6331, which prevented a drastic cut to physician salaries, mandated accreditation for performing CT and MRI scans, and defined appropriateness criteria for medical imaging. We also had detailed discussions on health reform and the importance of radiology in modern medicine. Recently, I arranged for Congresswoman Anna Eshoo to visit the Department of Radiology this fall.
My interactions with U.S. congressional representatives reminded me how critical it is to maintain and support government relations as our legislators can make broad sweeping changes with only a limited amount of information because they are dealing with such a broad range of issues. In many of my interactions with Congress and the Senate, I felt that I was providing new information to them. For example, several were not familiar with the fact that radiologists do NOT self refer and, thus, have little power over imaging growth. In addition, I educated them on the fact that radiologists have replaced many archaic diagnostic and therapeutic exams, which has led to cost savings and better health outcomes.
I believe that political advocacy is paramount for all radiologists and, that in the future, their patients' health may depend on such vigilance."

Stacey Crawford Keel, MD, MBA

Stacey comes to us from Ohio, where her father is a radiologist, which may have sparked her interest in this field. After a successful career at Northwestern, she completed her medical education at Dartmouth Medical School while simultaneously pursuing her MBA at the Tuck School of Business. She plans to pursue a career influencing medical education by integrating the organizational behavior and general management skills of the MBA into the curriculum for physicians-in-training. In her free time, she indulges in her love of animals by volunteering at her local humane society, as well as taking care of her own dog and two cats. She is a big fan of outdoor sports and enjoys traveling, especially to visit her extended family.
Bao Do, MD

Bao comes from the University of Iowa but grew up in Silicon Valley, where he was heavily influenced by technology. However, he chose to study biochemistry and economics at the University of California, Davis, over electrical engineering and computer science at the University of California, Berkeley, because the last thing he wanted to do was sit in front of a computer all day. Alas, fate has caught up to Bao as he pursues radiology. Ironically, he is currently developing a "negation" search algorithm with his friend Andrew Wu that explicitly finds the exact opposite of what a user wants. Bao's other interests include web programming, the NBA, and sushi. Bao will be joining our third-year class in July.
Chivonne Harrigal, MD

Chivonne was born in New Orleans and also grew up in Bakersfield, Denver, and Dallas. She earned her BS and MD degrees from the University of Pittsburgh. She began her residency at the University of Arizona, but she is transferring to our program to complete it. Chivonne will join us July 1, 2008, as a second-year resident. When she has time, she pursues her interests in running, scuba diving, cooking, and traveling.
Albert Hsiao, MD, PhD

Albert is happy to join his radiology colleagues after a year of general surgery internship at Stanford. After studying science and engineering at Caltech, he chose to enter medical school at the University of California, San Diego, where he completed a PhD program in bioengineering. He spent much of this time studying math, physics, and computation, visiting his soon-to-be wife at Stanford, training in martial arts, playing tennis, and surfing. He eventually completed medical school, got married, adopted cats, and spent a productive year learning general and subspecialty surgery.
Michael JJ Kim, MD

Michael was born and raised in Nutley, New Jersey, where he stayed close to home for his undergraduate career at Rutgers University, graduating summa cum laude with a degree in genetics. Afterwards, he attended Weill Medical College of Cornell University in New York City, where he developed his interest in radiology and met his fiancee. "JJ" recently became engaged, surprising his fiancee with a loudspeaker balcony proposal where they first met at Barnes and Noble in Nutley. For fun, Michael enjoys many sports including tennis and golf, sharing new experiences with friends and family, and learning about public policy issues.
Deborah Lee Abelson, MD

Debbie, from southern California, went to the University of Southern California for her undergraduate degree. She received her medical degree from the University of California, Los Angeles, David Geffen School of Medicine. When not working, Debbie enjoys spending time with family, exploring the Bay Area, travelling abroad, and learning guitar.
Jared Narvid, MD

Born in California, Jared attended Yale University as an undergraduate. He earned his medical degree at the University of California, San Francisco. When not involved in research, Jared entertains himself by bicycling, playing tennis, roasting coffee, and playing jazz guitar.
Srihari Sampath, MD, PhD, MPhil

Srihari is a southern Californian. He completed his BA and MD degrees at Cornell University; his MPhil at the University of Cambridge; and his PhD at the Rockefeller University in New York. He is now excited to return to the Palo Alto underground, where he plans to pursue his interests in radiology, the Lakers, and indie rock. Srihari joins us at Stanford with his twin, Srinath Sampath, who is also in radiology.
Srinath Sampath, MD, PhD, MPhil

Srinath, a native Californian, earned his BA at Cornell University. He went on to complete his MPhil at Cambridge University in the United Kingdom; his PhD at the Rockefeller University in New York; and his MD at Cornell University Medical College. When asked to describe himself, Srinath offered the following: "When not actively having my life's dreams appropriated by my brother, I like to relax listening to classic and indie rock--either that or surfing PubMed. And though I don't always drink beer, when I do, I prefer Dos Equis." Srinath is here with his twin, Srihari Sampath, who is also in radiology.
Anobel Tamrazi, MD, PhD

Anobel started out in the Bay Area and attended San Jose State University for his BS. He earned his PhD from the University of Illinois at Urbana-Champaign, and his MD from the University of Illinois College of Medicine. He did his internship on the East Coast before returning to California for his radiology residency. When he gets a break in his schedule, he enjoys traveling and photography.
Amy White, MD

Amy is a returning California native. After earning her BS at the University of California, Santa Barbara, she studied for her MD at Georgetown University School of Medicine. She is sure to find a welcome home for her interests here, as both she and her husband are avid cyclists. In her remaining spare time, she enjoys practicing yoga.

Announcements: March 3, 2008
Dr. Alexej Jerschow to Deliver Talk Entitled "23Na and 1H CEST MRI: Contrast in Cartilage and Intervertebral Disc": Friday, March 7th, at 10:00 AM in the Clark Center Auditorium. Associate Professor Alexej Jerschow, from the Department of Chemistry at New York University (NYU), will be visiting Stanford on March 7th to give a talk on his novel work at high field. He will be visiting the Lucas Center afterwards to see our facilities and to meet our scientists over lunch. For more information, please see his abstract below and/or contact Dr. Garry Gold.

ABSTRACT:
Glycosaminogycan (GAG) plays numerous vital functions in the human body. GAG concentration [GAG] in vivo is a sensitive biomarker indicative of both osteoarthritis (OA) and intervertebral disc (IVD) degenerative diseases. By exploiting the exchangeable protons of GAG, we demonstrate that one can directly map the localized GAG concentration in vivo using a chemical exchange saturation transfer (CEST) method. This gagCEST approach is presented on both human cartilage and animal discs. We also show the observation of the Nuclear Overhauser Effect (NOE) from macromolecules in tissue, which contributes significantly to the CEST/MT contrast mechanism in MRI and may lead to further diagnostic abilities. GAG contrast may also be enhanced by employing intermolecular multiple-quantum coherences.
Monitoring the bound sodium pool can be an important tool for assessing the onset of tissue disorders. Practical clinical 23Na MRI methods, furthermore, often do not allow one to use sufficiently small voxel sizes such that only the tissue of interest is seen, and a large signal contamination can arise from sodium in synovial fluid. Methods are presented for the clean separation between the signal from bound or ordered 23Na over that of free 23Na, which is particularly important and can greatly enhance the potential of 23Na-MRI as a diagnostic tool. 23Na MRI also offers the possibility of monitoring local anisotropic motion. 3T and 7T in vivo volumetric 23Na images are presented. Monitoring GAGs via 23Na or CEST can also be important for assessing heart valves or corneae.

The Richard M. Lucas Center for Imaging Celebrates Over 15 Years of Service

The Richard M. Lucas Center for Imaging in 1992 (left) and 2008 (right).
By Julie Ruiz, PhD

At the dedication of the Richard M. Lucas Center for Magnetic Resonance Spectroscopy and Imaging on May 19, 1992, the Nobel Prize winner in chemistry from Zurich, Switzerland, Professor Richard Ernst, envisioned no limits to MR technology: "The only property of the body that one hasn't found with MR is the soul." While we still haven't imaged the soul, our imaging technology has greatly advanced since the opening of the Lucas Center 15 years ago.
The Lucas Center emanated from Dr. Gary Glazer's vision of creating a premier imaging research program to enhance the clinical research efforts of the Department. When he became chair of Stanford Radiology in 1989, the diagnostic radiology offices and research space were limited to one basement corridor in the Grant Building. Dr. Glazer invited Drs. Gary Glover, PhD, and Norbert Pelc, PhD, to Stanford to form a basic science team. They initiated the beginnings of the Radiological Sciences Laboratory (RSL), which was first housed in the Grant Building and then moved to the Lucas Center upon its completion in 1992. Donna Cronister was hired in 1990 as the RSL administrative services manager and became the administrative director for the Lucas Service Center in 1992.

Construction of the Lucas Center began in 1990 funded by the Richard M. Lucas Foundation. Don Lucas, venture capitalist and Stanford graduate, had started the foundation in honor of his older brother, Richard, who died of cancer in 1981. The Lucas Center was finished by 1992, adding approximately 12,500 square feet to our Department. Scientists at the Lucas Center in 1992 conducted 30 research studies using one 1.5T MRI scanner (human); one 4.7T MRI (animal); and one 9T MRI scanner (tissue). The total NIH funding in 1992 was about $1 million.

(Don, Mary, and John Lucas with Peter Bing (L) at the 1992 dedication ceremony for the opening of the Lucas Center. John, Mary, and Don (R) in front of the bust dedicated to Richard M. Lucas.)
By 1993, RSL had doubled the number of its faculty by adding Sandy Napel, PhD, in 1991 and Michael Moseley, PhD, in 1993. Dan Spielman, PhD, joined RSL as a research affiliate in 1990 and became an assistant professor in 1993. There were also two postdoctoral fellows and six scientific staff members including Tom Brosnan, PhD; Lori Pelc, PhD; and Anne Marie Sawyer, RRT.
In the years following its opening, the Lucas Center experienced unprecedented growth. In 1995, Dr. Glover received funding from the National Cancer Institute (NCI) to launch a full-scale academic radiology training program at the Lucas Center: the Center for Advanced Magnetic Resonance Technology at Stanford (CAMRT). Funded through 2010, the CAMRT joins the resources of RSL with those of the Electrical Engineering Department's Magnetic Resonance Systems Research Laboratory. From 1997 to 1998, the Lucas Center was expanded, adding 5,000 square feet to its facilities. As part of this expansion, the 3D Medical Imaging Laboratory, which had been in the Grant Building, moved to the Lucas Center, and we became one of the first research programs to install a 3T MR magnet.
(Pictures from the first expansion.)






The second expansion of the Lucas Center occurred between the years 2003 to 2005 and added an additional 20,000 square feet of space, making our Center one of the world's largest academic centers for medical imaging. With the second expansion, the Lucas Center also acquired a 7T whole-body magnet; a cyclotron to produce isotopes; more wet labs and offices for developing our Molecular Imaging Program at Stanford (MIPS); and a unique education center equipped with the latest technology for fully interactive imaging seminars. Because of its high quality and innovative design, our Center received the 2007 Design Honor Award: Excellence in Architecture from the American Institute of Architects (AIA), San Francisco Chapter (http://www.aiasf.org/Programs/Awards_Program/Design_Awards.htm).

(2004 view of the Lucas Center from the roof during the second expansion.)
After fifteen years and two expansions, the Richard M. Lucas Center for Imaging now houses 15 faculty members in RSL; 2 radiology faculty members in the Molecular Imaging Program at Stanford (MIPS); and over 70 graduate students and postdoctoral scholars. During the past year, our scientists conducted over 300 studies on our three magnets (a 1.5T, 3T, and 7T). With the remarkable increase in scanning speed and resolution of the 7T, we are imaging brain structures that have not been visualized before. We have also initiated two new research programs: high-intensity focused ultrasound and hyperpolarized C13 MR.

Since the opening of the Lucas Center, we have expanded our scope beyond MRI to include cellular and molecular imaging, moving us into the era of nanotechnology. To reflect the extension of our scope, the Lucas Center was renamed the "Richard M. Lucas Center for Imaging" in 2007. The Richard M. Lucas Center has also grown into a major resource for service in medical imaging. From January 1, 2006, to February 28, 2007, the Lucas Center supplied imaging services to over 70 projects and to 45 principal investigators (PIs).
Those who were present at the inception of the Lucas Center shared their impressions. Dr. Glover remembers standing in his Grant Building office just before the move into the new Lucas Center in 1992 and talking with Gary Glazer, MD, who asked him, "Did you ever think we'd get this big?" Gary Glover responded, "No, not to the point of needing a new building." In fact, shortly after the move into the Lucas Center and after each expansion, the Lucas personnel quickly outgrew their space. "The enthusiasm and excitement surrounding our research is fueled by having the best faculty and students in the world and incredible support from Gary Glazer," Gary Glover remarked. "Most radiology research programs do not have the support our lab has received from their Department chairs. Gary has made it easy for me and my colleagues by fostering such a large investment in research. Indeed, he has been the driving force behind the success of our Department's research enterprise. One result of his vision and enthusiasm for research is that we have retained all but one of our faculty over the past 18 years."
Gary Glover has tried to grow the RSL and Lucas Center and still retain a community: "It's harder maintaining cohesion with 90 people as opposed to 10 people, but I think we have succeeded in keeping comradery and closeness." Reflecting back on his years as part of RSL, Tom Brosnan, PhD, also remembers how small the lab was in 1991: "There weren't enough people for a softball team, but every Friday at 5 PM we had a party and everyone brought food. We even had an annual lab ski trip, but the lab is too big for that now." When RSL moved from the Grant Building to the Lucas Center in 1992, Dr. Brosnan thought, "We'll never fill up all of this space!" The biggest change for him has been the significant growth in personnel and in the nature of his projects: "There are more projects to do now, and they are more complex. In retrospect, the work I did initially for RSL seems simpler than what I'm doing now."
In the future, we anticipate "Lucas Three," the third expansion of our Center to support growth in anatomic imaging, molecular imaging, and nanotechnology. We will continue to promote interdisciplinary translational research through our recent "Academic Initiatives": the Stanford Center for Early Neoplasia Detection; the Aging Brain and Cognitive Disorders; and Image-Guided Therapy. Our investments in our translational research efforts have already resulted in the establishment of three NIH-funded centers that complement the efforts of the Lucas Center: the Center for Advanced Magnetic Resonance Technology (CAMRT); the In Vivo Cellular and Molecular Imaging Center (ICMIC); and the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR). As we continue to build better tools for imaging structure and function, we hope to make a large impact on medicine and biology.

Dr. Lawrence "Rusty" Hofmann Featured in AuntMinnie.com

Rusty Hofmann, MD, chief of interventional radiology, was recently featured in an AuntMinnie.com article by Edward Susman, "Imaging Set to Play Pivotal Role for Delivering Molecular Therapeutics." The article is based on Dr. Hofmann's presentation at the 2008 International Symposium on Endovascular Therapy (ISET) meeting in which he highlighted the importance of imaging in molecular therapeutics: "In human trials, there is no way to monitor the appropriate site to inject the drugs, to monitor delivery of the drugs, to monitor how the drugs traffic in the body, and no way to monitor how those drugs engraft." The injection of molecular agents in combination with imaging guidance can help resolve these problems by improving drug delivery. For the full text of "Imaging Set to Play Pivotal Role for Delivering Molecular Therapeutics," please access http://www.auntminnie.com/print/print.asp?sec=sup&sub=adv&pag=dis&ItemId=79852&d=1.
ISET celebrated its 20th anniversary at the 2008 conference in Hollywood, Florida. Attended by leaders in interventional cardiology, interventional radiology, and vascular specialties, this conference provides the most current noninvasive techniques for the diagnosis and treatment of vascular diseases through live case demonstrations. Conference presentations included ground-breaking research on topics such as gender differences in the endovascular repair of abdominal aortic aneurysms; outpatient uterine fibroid embolizations; the benefits of treating pregnant women who have DVT; and the use of anti-platelet therapy to reduce the risk of heart attack and stroke in PAD patients.

Title:
"Detection of Change in Serial Magnetic Resonance Studies of Brain Tumor Patients"
Abstract:
The comparison of serial magnetic resonance imaging studies is a common task in clinical radiology. It is, however, widely considered not to be very reproducible. There are a variety of reasons for this, including the confounding of disease-related changes with acquisition-related changes and issues related to information presentation. We have constructed a computational system that performs the comparison of serial magnetic resonance imaging studies and presents changes in the form of a color-coded change map, superimposed on the anatomical images. The system additionally formats the output as a quantitative summary. We used this quantitative summary to conduct a study with 88 brain tumor serial comparisons. Our results were suggestive that it may be possible to use the change detector to identify cancer changes months earlier than is possible using manual inspection, alone.
We have recently implemented an integrated system for the change detector, which includes a graphical user interface (GUI). The GUI not only displays the color-coded change map, but also allows the user to turn it on and off. The GUI provides linked cursors, and it additionally provides "flicker" functionality to allow the user to rapidly alternate between the serial acquisitions. We are preparing to deploy the GUI change detector clinically, which will greatly increase the size and variety of possible future research studies and which will allow the direct clinical application of this technology.
The change detector is an example of a layered artificial intelligence (AI) architecture in which each layer builds upon the layer below, with each layer accomplishing progressively more sophisticated analyses. Specifically, the change detector is built on a lesion-finder application. The lesion finder is built on an automated sample point's algorithm. The automated sample point's algorithm is built on a significant region detection algorithm. Each of these algorithms has merit in its own right, and each can be used in a modular fashion in a variety of contexts. As a unified application, they together automatically address a complex clinical task. Early detection of changes may facilitate improved care through more rapid intervention following recurrence. It may also facilitate screening and personalized therapy. We additionally see the change detector as providing a solution to the problem of novel therapy comparison, by providing fully automatic, reproducible, and quantitative measures of change. We envision the change detector as a model of layered artificial intelligence, not only freeing the radiologist from the drudgery of information overload, but providing a model whereby greater information will enable many sophisticated automatic analyses by the computer, with the computer bringing to the attention of the clinician only what is relevant.

Title:
"Virtual Biopsies: Non-Invasive Molecular Diagnosis"
Abstract:
Our expanding knowledge of the genetic basis and molecular mechanisms of cancer is beginning to revolutionize the practice of clinical oncology. Increasingly, molecular biomarkers of prognosis and treatment response are being used to classify tumors and direct treatment decisions. Advanced medical imaging platforms such as MRI, PET, and CT provide incredibly detailed images of tumors that reflect their structure, biochemistry, physiology, and perhaps genetics.
Studies by the Imaging Informatics Lab at the University of Calgary, and others, show that information about a tumor's molecular phenotype can be obtained by using novel algorithms and computational tools to more fully analyze tumor images. Such "virtual biopsies," performed by applying these image-processing techniques to routine diagnostic images (e.g. MRI, PET, or CT), could be a rapid and powerful means of assaying important cancer biomarkers. If successfully validated, and proven to have suitable sensitivity and specificity, the use of non-invasive, imaging-based molecular diagnostic tests would offer significant advantages over conventional surgical biopsies. For example, this could be important in the context of large heterogeneous tumors, multiple metastases, surgically inaccessible tumors, and settings where disease progression needs to be monitored frequently over time. Virtual biopsy research lies at the intersection of molecular imaging, medical imaging physics, and biocomputation, and is highly complementary to these areas. This presentation will cover key enabling technologies behind virtual biopsies and discuss some recent successes in this research.

Title:
"Dynamic Chest Image Analysis, United Snakes, and
Computer-Aided Detection"
Abstract:
Modern medical imaging systems generate enormous datasets with ever higher coverage and resolution, but it is the clinically relevant information in these images that is paramount. I shall present several novel computational approaches for gleaning such information from chest X-ray images to reveal pulmonary functional abnormalities, for segmenting and characterizing organ motions, and for detecting the most lethal diseases from CT images, including pulmonary embolism and colonic polyps. The former approach has yielded model-based analysis and visualization methods for revealing focal and general abnormalities of lung ventilation and perfusion based on a sequence of digital chest fluoroscopy frames collected with the dynamic pulmonary imaging (DPI) technique.
In particular, I shall present a novel multiresolutional method with an explicit ventilation/perfusion analysis model, as well as "United Snakes," an interactive deformable model framework for lung registration and motion analysis, cardiac shape and motion analysis, and other applications. Finally, I will introduce a fast yet effective concentration-oriented tobogganing technique for efficient local artery/vein separation and multiple instance classification for the automated detection of pulmonary embolism from CT pulmonary angiography (CTPA), and a virtual colonoscopy technique that simplifies the complex 3D-polyp detection problem into a 2D-disk identification problem, significantly improving sensitivity while reducing computation time.

Title:
"Imaging Informatics: From Bench to Bedside and Beyond"
Abstract:
Vast amounts of knowledge lie within the grasp of radiology researchers and practitioners to help them to understand disease and to practice effectively, but much current biomedical knowledge is not being accessed and utilized. The explosion in images and non-imaging data is challenging the ability of radiology researchers to identify and to pursue promising new investigational directions. The latest results that researchers produce are not always informing radiologists in their day-to-day work, as there are few tools to help them to identify, retrieve, and use pertinent clinical and research knowledge at the point of care. Consequently, there is variability among radiologists in their clinical effectiveness, and opportunities for translating new discoveries into practice are being lost. The methods and tools of biomedical informatics are enabling biologists to cope with similar problems arising from the information explosion in biology, and they are adopting informatics techniques to function effectively in the e-Science era.
In this presentation, I will discuss ongoing work to develop and apply biomedical informatics techniques to meet the information challenges in radiology. Specifically, knowledge representation, semantic annotation, statistical natural language processing, data integration/warehousing, computer reasoning, and decision support are key directions in informatics needed to create intelligent applications for radiology. Future advances in radiology will lie at the intersection of imaging science and biomedical informatics. The new computer applications that emerge will change clinical imaging workstations into knowledge portals and enable radiologists to keep pace with new discoveries, to exploit new radiology knowledge, and to practice more consistently and effectively.

"A Data-Driven Approach Toward Knowledge Discovery and Improving Healthcare"
Abstract:
Radiology and biomedical informatics are revolutionizing healthcare. It has been predicted that a shortage of trained radiologists will continue in the next three decades. Effective computerized tools will therefore be in great demand. Radiology departments today generate an incredibly massive amount of digital medical images and metadata. Conventional PACS search methods allow physicians to locate images using metadata stored in relational databases. Much more can be done to leverage this wealth of data. Using massively parallel computers, we can mine millions of electronic medical records and millions of high-resolution, high-dimensional, multi-spectrum medical images to draw conclusions statistically based on past cases. We need to invent computational methods to harness the breathtaking quantity of digital information effectively and to generate biomedical knowledge at a pace we could not have imagined. In the last decade, my research group attempted to reduce the significant gap between low-level features extracted from images and high-level semantic concepts. Machine learning, statistical modeling, and mathematical tools have been utilized. I will introduce some of our past research results of relevance to the radiology community. Specifically, the talk will cover the SIMPLIcity visual similarity search, the 3-D hidden Markov models for analyzing volume images, the Automatic Linguistic Indexing of Pictures system, and the ontology-based annotation and retrieval of histological images and quantitative phenotypes. In the coming years, I plan to collaborate with radiologists, physicians, and biologists in order to develop indexing, retrieval, and mining algorithms and systems for large amounts of radiological images and patient-specific data.

Tsinghua University's "Oversea Expert," Dr. Gary Glover

As he jogged along the banks of the Wanquan River sharing the path with a swarm of bicyclists, Dr. Gary Glover wound through the campus of Tsinghua University in the northwestern suburbs of Beijing. Selected by Tsinghua University as their "Oversea Expert," Dr. Glover came to the University to share his scientific expertise and knowledge with their faculty and students as they initiate their own MRI program. He brought graduate student Catie Chang with him for part of the trip.
Sponsored jointly by the National Office of Foreign Experts and the Department of Education, Tsinghua's "Oversea Expert Program" is designed to bring "recipients of important international awards . . ., professors of world-renowned universities, and other established experts who have a great reputation in their corresponding international research community" to help train students and faculty in MR research and program design as well as to offer specialty courses and to provide guidance and consulting for research projects. Tsinghua University has over 20,000 students (including 12,000 undergraduates, 6,200 master's degree candidates and 2,800 doctoral candidates) and approximately 8 colleges, 43 departments, 44 research institutes, 9 engineering research centers, and 163 laboratories. The University also offers 37 bachelor's degree programs, 107 master's degree programs, and 64 PhD programs.
Karen Ying, PhD, associate professor in the Department of Engineering Physics and the Medical Physics and Engineering Institute, extended the invitation honoring Dr. Glover as Tsinghua University's Oversea Expert, who is to return annually for one month each year for a total of three years to provide scientific expertise and continuing guidance for Tsinghua's MRI program. Dr. Ying teaches a graduate course on the principles of magnetic resonance imaging. She and her three undergraduate and three graduate students comprise the whole MR imaging program for the University. They have no scanners; all MR and CT research is done at local hospitals. The University is constructing a medical school.
Dr. Ying has been a professor at Tsinghua for two years; prior to that, she taught and researched in the United States for ten years. Her father has taught in Tsinghua's Department of Engineering Physics for over 57 years. In talking with him, Dr. Glover learned that during the Cultural Revolution under Chairman Mao's reign, Dr. Ying's father was forced to quit the University and work on the farms for one and a half years. Although a professor emeritus, he still has five graduate students with whom he works.
During his visit from November 15th to December 5th, Dr. Glover gave 9 two-hour class lectures, and Ms. Chang gave 2. His lectures covered such topics as pulse sequence design and fast imaging techniques; the principles of diffusion/perfusion MRI and flow imaging; and functional MRI. He described the building in which he lectured as "gigantic with hundreds of classrooms that were busy from 0 o'clock in the morning until N o'clock at night." "Even as I walked around at 9 PM," Dr. Glover remarked, "there were students in the classrooms studying. There was a constant bustle of people around me, and bikes where everywhere at all hours; there were few cars on campus and no students' cars."
In addition to his lectures, Dr. Glover held two public evening colloquia and three meetings with University officials including the university president, provost, Vice President Ke-Jun Kang, Medical School Dean Zhao, and the Department of Engineering Physics Head Tang Chuanxiang. One topic he and the University faculty and administration discussed was the possibility of a foreign exchange program for graduate-level research/education between Tsinghua and Stanford to foster strong collaboration between our two institutions. He also spoke at a meeting with General Electric regarding research collaboration between GE, Stanford, and Tsinghua.
Established in 1911, Tsinghua University was built on the site of "Qing Hua Yuan," a former royal garden of the Qing Dynasty. Dr. Glover stayed at the guest house, which was across from a small island known as Jinchun Garden, where the eighth emperor of the Qing Dynasty, Xian Feng, had lived. From 8 AM until about 10 AM, Dr. Glover was greeted by the sights and sounds of people dancing to traditional Chinese music in the -20 degrees Fahrenheit weather in Han Pavilion of Jinchun Garden, which is surrounded by a lake with scenic bridges.

Han Pavilion
Also undaunted by the cold weather were the "pillbox" guards who stood watch over the campus from 6 AM until around 11 PM.

During his visit, he was amazed by the excellent customer service he received, "I went into the equivalent of a 'Best Buy,' and there were 27 clerks in the camera department waiting to help me. In the local pharmacy, there were 11 clerks--one every foot and a half of counter space. When my card key didn't work in my hotel door, two people and part of a third person came to remedy it after an extensive discussion. The service was wonderful!" While the customer service was excellent, the air quality was not: "I saw four power plants on campus burning coal; I never saw the sun; it was always filtered through the haze, and there were no stars at night. It was hard to breathe as I jogged on campus."
In his free time, Dr. Glover did some sightseeing in Beijing, a city of over 15 million people. He toured the Great Wall of China; the Forbidden City and its "Hall of Medium Harmony" (something has been lost in the translation); Tian Anmen Square; the Lao She Tea House; Fragrance Hill; the Sleeping Budha; the Botanical Garden; the Thirteen Ming Tombs; and the Chairman Mao Solemn Memorial. The streets were packed with bicyclists as most goods were transported by bicycle cart. While in Beijing, he also had the opportunity to visit a CT manufacturing site.
His visit to Tsinghua University was only part of his three and a half week "lecture circuit." Prior to coming to Beijing, Dr. Glover had flown to the University of Maryland where he gave two lectures: one on real-time fMRI and another on alternative fMRI methods. On his way home from Beijing, he flew to the University of Vancouver, B.C., to give another lecture because Judy Illes, PhD, the Canada research chair in neuroethics at the University of Vancouver and former director of grants in our Department, had invited Dr. Glover to give a lecture for their colloquium series.
Awards and Honors: December 17, 2007
2007 IEEE (Institute of Electrical and Electronics Engineers) Medical Imaging Travel Grant Winners Frances Lau, MS, Peter Olcott, and Guillem Pratx, MS, were awarded travel grants to present their novel and original work at the 2007 IEEE NSS-MIC (Nuclear Science Symposium and Medical Imaging) Conference in Honolulu, Hawaii.

Our own Donna Cronister was named this year's winner of the Marshall D. O'Neill Award for her exceptional and enduring support of Stanford University's research enterprise. Now in its 17th year, this prestigious and university-wide award is bestowed annually by the Office of the Vice Provost and Dean of Research in honor of Marshall D. O'Neill, associate director of the W.W. Hansen Laboratories from 1952 until 1990. Donna is the 27th recipient of this award.
"I was quite surprised when I took the call from Ann Arvin, vice provost and dean of research. I probably sounded like a complete idiot because I honestly did not know what to say," Donna remarked. "I am very honored just to be nominated, and I am very proud to be the 2007 recipient of the Marshall D. O'Neill Award."
While most 2007 award candidates were nominated by one or two faculty members, Donna was nominated by eight. Gary Glover, PhD, director of the Radiological Sciences Laboratory (RSL), described Donna's award as an "outstanding, University-wide endorsement of what we have all known for a very long time--that Donna is simply above exceptional in every way!"
Working with 12 faculty and over 80 graduate students, postdoctoral scholars, research assistants, and research associates, Donna manages each facet of the lab's research, which includes coordinating funding for researchers, organizing courses and conferences, and planning the budget. She is also involved in the day-to-day operations at the Lucas Center and oversees the payroll; reimbursement; accounting; personnel policies and procedures; building maintenance; supply ordering; and service policies.
These are just a few of the many tasks for which Donna has been responsible since she came to Stanford in 1990 after working in the corporate world:
"My husband and I moved to California from Montana in 1980 after the birth of our twin daughters. I was a stay at home mom until the girls were about two and a half years old. When my husband came home and found me lying on the back of the couch so they couldn't get to me, we decided it was time for me to go back to work! I worked for three years for a chemical company and then moved on to Xerox where I worked for about eight years. During this time, we added another daughter to the family. Xerox had a massive reduction in force, and I took about six months off before applying at Stanford.
The rest, as they say, is history. I have been with the Radiological Sciences Laboratory since February 1990. We have seen our lab grow from Gary, Norbert, and me to about 90 folks now! I oversee the lab, and I am also the administrative director for the Lucas Service Center." When she's not at work, Donna loves to garden and to spoil her grandson and granddaughter. "Life couldn't be better for me," she added.
Dr. Gary Glover extended an invitation to attend Donna's November 12th reception to "every one of the hundreds of students, faculty, and everyone else who knows or has been touched in ways large or small by Donna over the years." At her reception at the Faculty Club, Associate Dean of Research John Brauman presented the Marshall D. O'Neill Award to Donna on behalf of the vice provost and dean of research, Ann Arvin.

Lifetime Achievement Award: Dr. Henry H. Jones

(Image courtesy of Mark Riesenberger)
"My greatest achievement is that I survived," Dr. Jones said to me after I spoke with him about our "Lifetime Achievement Award." In his 68 years of serving Stanford Radiology, Dr. Henry H. Jones, professor emeritus, has done much more than survive. He has left a long legacy of achievements and a lasting impression on those who have had the opportunity to interact with him.
Born on June 9, 1917, in Altoona, Pennsylvania, he was the second son of Henry O. and Euphemia Heilman Jones. His older brother, Howard, died in infancy. His father was a urologist, and his mother was the superintendent of music for the Altoona school system and, later, was a writer of style reviews and producer of fashion shows for the William F. Gable Department Store. "She was so successful," Dr. Jones told me, "that department stores as far away as Pittsburgh wanted to hire her to produce their style reviews."
After graduating from Haverford College in 1939 with a BA in chemistry, Dr. Jones attended the graduate chemistry program at Harvard. "I spent a year pretending to be a chemist at Harvard and learned that I wasn't really going to be the kind of chemist I wanted to be because I didn't fully comprehend the application of partial differential equations." In 1940, he applied and was accepted to medical school at Yale. In medical school, he was reminded that medicine requires a life time of learning, which is something he had observed throughout his childhood because both his father and grandfather were physicians. "In your first- and second-years of medical school, you realize that what you are learning today you will use for the rest of your life," Dr. Jones remarked. Because of his interest in chemistry and mathematics, Dr. Jones felt a natural affinity for radiology.
At the end of 1941, he was inducted into the army to serve in World War II, but he was assigned back to finish his medical studies. After completing a rotating internship in 1943 at Metropolitan Hospital in New York City and a residency in radiology at Yale in 1946, he served in the army as an instructor at the Army School of Roentgenology at Fort Sam Houston in San Antonio, Texas, where he trained physicians to be radiologists or "90-day wonders," as they were commonly called. "That was a great experience," he told me. "I had just finished my residency in radiology and now I was teaching what I had learned. If you want to learn something, teach it!" After three cycles of training, he was assigned as head of radiology in Bad Constadt, Germany, which was the orthopedic center for the army of occupation.
After his discharge from the army in 1948, he went to speak with the chair of the Radiology Department at Yale, Henry Kaplan, MD, who had taught him during residency and who had recently been hired to head the Stanford Radiology Department. Dr. Jones' reputation preceded him, and it was the impression he had left on Dr. Henry Kaplan that led to his hire at Stanford. "After I was discharged from the army, I was looking for a position as an academic radiologist so I went to talk to Henry Kaplan. I asked him, 'Do you know of any available academic jobs in radiology?' He answered, 'Why? You already have one at Stanford.' It's the only job application I've ever done in my life! It was very inexpensive; I didn't fill out any forms or anything." So, Dr. Jones came to Stanford at the end of June 1948. Because Dr. Kaplan did not leave Yale for Stanford until September, Dr. Jones ran the Department until his arrival. As the only senior, full-time faculty member, he worked 7 days a week for 14 to 16 hours a day, and he taught all the radiology courses until Kaplan arrived in September of 1948.
After 68 years in our Department, he has left an enduring legacy and the results of his life time of learning are reflected in the plaques that line the walls of his office, such as the Robert Reid Newell Memorial Award and the Broad Street Pump Award. Conferred by Physicians for Social Responsibility (PSR), the Broad Street Pump Award is bestowed upon physicians who apply their medical knowledge in socially responsible ways. Dr. Jones was a founding member of PSR and a leader in the movement to eliminate nuclear war and weapons of mass destruction. "I was very surprised and extremely pleased. I'm delighted to have this award," he commented. Dr. Jones was also the first chief of the radiology service at the Palo Alto Veterans Administration Hospital, and he earned the moniker "Bones Jones" in recognition of his subspecialty regarding the skeletal system. His research focused on the mechanisms governing the growth and modeling of the skeletal system.
Dr. Jones has accumulated a great number of roentgenograms throughout his career, and he has donated them to our departmental resident and medical student teaching library: "I used to teach the bone and joint part of the radiology clerkship, and I have bequeathed the set of films I accumulated through my teaching to the library for use by the medical students and residents. I think it's useful, and it's organized so that people can teach themselves. People do very well teaching themselves by the time they get to medical school. If you can't teach yourself by then you're in deep trouble." The Stanford University Medical Media and Information Technologies (SUMMIT) is compiling his extensive collection of radiographs. For more information on this project, please see http://summit.stanford.edu/pdfs/mediaserver_ts.pdf and http://summit.stanford.edu/pdfs/meadiaserver_tearsheet.pdf. His collection is also featured in Dr. Amy Ladd's Paget's Disease E-Book, which can be viewed at http://paget.stanford.edu/, and he has given several detailed and informative online lectures on bone disease, including one on osteomyelitis (http://osteomyelitis.stanford.edu/pages/hjones.html) and one on osteosarcoma (http://osteosarcoma.stanford.edu/pages/EbookInfo.html).
After retiring on December 31, 2006, he worked part-time until January of 2007. I asked him how he spends his time, and he told me, "I'm reorganizing my film collection, and I'm cleaning my desk, which could take a while. I make a little progress on it, and I come back to find it's grown back again; I don't understand how it piles up, but it does." He also enjoys spending time with his grandchildren, Emmerson (age 11) and Elliott (age 6).
To read more about what our Department was like when Dr. Jones began at Stanford, please see his first-author publication, "A History of the Department of Radiology at Stanford University" published in the American Journal of Roentgenology 1995 Mar;164(3):753-60 (http://www.ajronline.org/cgi/reprint/164/3/753).

2007 RSL Post-Retreat Update


By Julie Ruiz, PhD
(thanks also to Donna Cronister and David Paik, PhD, for their contributions to this article)
The RSL had another productive and fun retreat at Asilomar this past September (for the pre-retreat blog article, please see http://radiology.stanford.edu/blog/archives/2007/09/2007_rsl_retrea.html). Among the highlights were the group introductions. Like last year, the group introductions were informative as well as entertaining. This year, each RSL group was asked to create an advertising campaign--a TV, radio, web, or print ad--to explain what the group does and why it is important. You can view the introductory presentations from the groups of Drs. Norbert Pelc and Dan Spielman at http://www.stanford.edu/~smazin/pelcgroupintro2007/inversitis.wmv and http://www.stanford.edu/~pritib/MRSvsMRI.wmv, respectively.

Our guest speakers included Thorne Lay, PhD, professor in the Earth Sciences Department and director of the Center for Studies of Imaging and Dynamics of the Earth at the University of California, Santa Cruz, and Dr. Kelly Skeff, professor of medicine (general internal medicine). Dr. Lay delivered our key note address on geophysical imaging. He discussed how scientists infer the structure of the earth's core by looking at the seismic data collected worldwide; he also addressed the challenges involved in the visualization of their data. Dr. Skeff's presentation on good teaching practices produced a very interactive discussion about teaching, which was applicable to all kinds of pedagogy.
Other highlights included RSL Family Feud; karaoke night; a photo contest; an RSL sweatshirt for retreat participants; and a productive town hall meeting.

Norbert

Wendy
Donna Cronister summarized the items raised during the RSL town hall meeting as follows:
"1. Key operator for printers, copiers/fax machine: Designate a person on each floor to maintain the printers/copiers. This does not mean simply replacing empty toner cartridges but keeping an eye on the equipment to insure that the proper supplies are on hand and that the equipment is operating properly (i.e., high copy quality, not jamming, etc.).
2nd floor: 4 printers/1 copier/1 fax (Marlys is the key operator).
1st floor: 4 printers (1.5T and 3D Lab--soon to be 5 printers when the second 3T comes online; 1 copier (1.5T). Keesha is responsible for the 3D Lab printers. Anne, Sandra, and Romi are responsible for the printers located in magnet suites.
Basement: 3 printers (including the 3T magnet suite)/1 copier/1 fax. Sharon will be the key person for the copiers at this level. Marlys will keep an eye on the copier.
Sublevel: 2 printers (including the 7T magnet suite)/1 copier (Lanzie's office)/1 fax. Lanzie will be responsible for the copier, fax, and printer in PS055. Anne, Sandra, and Romi will be the contacts for the 7T magnet.
2. Stocking kitchens: Designate a person on each floor to keep the kitchen stocked with plates, napkins, cups*, utensils, and coffee/tea supplies. Marlys has an order for regular delivery of coffee, creamers, etc. If we run low on supplies, please contact her. Marlys will maintain the kitchen on the second floor. Sharon is our basement stocker, and Lanzie is our sublevel stocker!
*The subject of paper cups stirred a rousing conversation about conservation. We would like to change our attitudes about using paper cups. Everybody must have a mug at home they can donate (e.g., 'World's Best Mom'; 'I Heart You'; etc.); you know the mugs I am talking about. If you do not have a cup or cannot afford a cup, then a cup will be provided to you free of charge. Of course, a real cup requires real washing, but we are adults, and nobody would have to be reminded to wash their cup and put it away!
3. Recycling: We have recycling bins/barrels located in strategic areas throughout the center. Please use them. At the entrance of each galley located on the Medical School Lab Surge (MSLS) side of the building are large recycling barrels for cans/bottles and mixed paper. If you do happen to see an overflowing recycling bin in our area, please do not hesitate to empty them into these barrels. The barrels are on wheels and, therefore, are mobile, and they can be moved to your area if you have a large scale paper clean up. The reason I do not have them located on our side of the building is because of the following: 1) SPACE and 2) Since the second floor is carpeted, I would rather that the dirty recycling barrels, which are emptied weekly by the Peninsula Sanitary Service, Inc. (PSSI), are not wheeled across the carpeting, especially in the muddy, rainy season. A small electronic waste receptacle is located near the basement elevator. If you need to recycle CDs, cell phones, pagers, small drives, zip drives, and memory sticks, this is the place to do it. These receptacles are emptied biweekly. Also, please recycle batteries in the small canister on the second floor. There are also battery recycling containers located at the MSLS galleys next to the large recycling barrels.
4. PCards and Reimbursements: I have asked Luis if he and I could present, at an RSL group meeting, a quick overview of what can and cannot be purchased with the PCard. Also, we will provide a travel 'cheat sheet' for you in order to reduce the amount of time for your reimbursement. This will explain what we can pay in advance, what documentation you will need when you have returned from the trip and request reimbursement, and WHY we need this documentation.
5. John has hung up two of the large pictures that were littering the hall.
6. John is looking into the best way to make the water cooler taller (6" or so) to accommodate some of our taller friends.
7. Somebody requested that Magnetic Resonance in Medicine (MRM) and Journal of Magnetic Resonance Imaging (JMRI) be added to the library. There is almost an entire MRI set down there already, including the really old ones when it was not a full-sized journal. Norbert offered to lend his bound set to the library as long as they do not walk off."

Awards and Honors: October 23, 2007

Garry E. Gold, MD, associate professor of radiology, was recently awarded the President's Medal for Outstanding Research in Bone and Joint Disease at the 2007 meeting of the International Skeletal Society. The President's Medal is given to members of the International Skeletal Society in honor of their outstanding scientific achievements on an international level. Recipients also receive a monetary award to support their research efforts.
Announcements I: October 2007
The Radiology Interest Group Presents "Careers in Radiology: Panel and Meet and Greet": Tuesday, October 30, 2007, at 6:15 PM. The Radiology Interest Group and the Department of Radiology will be holding the second annual "Careers in Radiology: Panel and Meet and Greet." The purpose of the event is to introduce medical students to what life is like as a radiologist. Members of the Radiology faculty, along with fellows and residents, will be there to answer medical students' questions such as Why become a radiologist? What is the balance like between home, life, and work? What are the subspecialties in radiology? What does an interventional radiologist do versus a diagnostic radiologist? The event will be held at Nexus Cafe at the Clark Center on October 30 at 6:15 PM (a light dinner will be served). Please email Rebecca Rakow-Penner (rakow@stanford.edu) to RSVP or to ask any questions about the Radiology Interest Group.

New Faculty Hires and Promotions: October 8, 2007

Patrick Barnes, MD, became a professor of radiology on September 1, 2007. Dr. Barnes received his medical degree from the University of Oklahoma College of Medicine, Oklahoma City, Oklahoma, where he was also a resident. After completing his residency, he became a fellow in pediatric neuroradiology and cardiovascular radiology at Children's Hospital and Harvard Medical School, in Boston, Massachusetts. Before coming to Stanford in 2000, he was an associate professor of radiology at Harvard Medical School and director of neuroradiology and MRI at the Boston Children's Hospital. At Stanford, he has been the section chief of pediatric neuroradiology and the medical director, MRI/CT, at Lucile Salter Packard Children's Hospital since 2002. He was chosen as the Senior Faculty of the Year for 2002-2003, 2004-2005, and 2005-2006 for his outstanding contributions to resident education, compassionate patient care, and research. Dr. Barnes has provided outstanding clinical, educational, and administrative leadership for the Neuroradiology and Pediatric Radiology Programs in the Department of Radiology, and he continues to help build the Developmental Neuroscience Program in the Department and at Lucile Packard Children's Hospital.

New Staff Hires and Promotions: October 3, 2007
Pam Hertz, RVT, joined our Department on August 6, 2007, as the new research veterinary nurse. She earned her certificate and diploma as a licensed registered veterinary technician in June of 1999 from Foothill College. Prior to coming to Stanford, she had been working in small animal veterinary practices since 1996. Her immediate supervisor will be Wendy Baumgardner, RVT, LATg, who will train her in the various areas of animal research and policy. Ms. Hertz says that she looks "forward to working with and learning from Wendy; she has been a great teacher." In her time off, she enjoys snow skiing, day hikes, golfing (she still needs lots of practice), and spending time with family and friends. Although she does not have any pets of her own now, she enjoys spending time with her friends' pets.
Celebrating 15 Years of Service: Keshni Kumar
Keshni Kumar, CRT, has worked at Stanford University for 15 years. At seventeen years of age, she began volunteering at Stanford Hospital and Clinics (SHC), when Dr. Rubin was a resident, to get exposure to the hospital environment. She attended Foothill College and Santa Clara University, and she graduated as a radiologic technologist. She has been working for Stanford Hospital and Clinics since 1992. Soon after, she was the lead technologist at Cowell Student Health Center (currently the Vaden Health Clinic) for two years and then served as the senior CT technologist at SHC for seven years. During Technologist Week, she won the Employee of the Year Award, which was a trip to Hawaii. She is now one of the top producers of the 3D lab, where she has been a radiologist assistant for three years. Ms. Kumar takes pride in her work: "I am very proud of how I contribute to patient care, which is why I still work at the Hospital as a relief CT technologist twice a month. I love challenging and intriguing new technologies." Her hobbies include teaching, running, hiking, and cooking.

Awards and Honors: October 1, 2007

Craig Levin, PhD, associate professor of radiology and leader of the Molecular Imaging Instrumentation Laboratory (MIIL), has been awarded a new R01, "Enhancing Molecular Cancer Imaging with Cadmium Zinc Telluride PET" from the National Cancer Institute. This projects consists of studying novel imaging sensors comprising a semiconducor material known as cadmium zinc telluride (CZT) and incorporating these sensors into an innovative configuration for an advanced positron emission tomography (PET) system designed for imaging small laboratory animal cancer models. The proposed system built with these CZT imaging sensors promises to enhance substantially the capabilities of PET to detect, visualize, and quantify low concentrations of molecular cancer probes reaching their target on or within cells of diseased tissues. If successful, this work will impact the development of new cancer imaging assays and help to guide the discovery of novel treatments for cancer. In the MIIL, Dr. Levin's research involves the development of novel instrumentation and software algorithms for in vivo imaging of subtle molecular processes associated with disease in the clinic as well as in small laboratory animal research. The goals of the projects are to enhance the photon sensitivity and spatial, spectral, and/or temporal resolutions in order to advance the ability to accurately detect and measure lower concentrations of molecular signal. The ultimate goal is to introduce these new imaging tools into studies of molecular mechanisms and treatments of disease within living subjects.
Becoming a U.S. Citizen
Have you ever wondered what it takes to become a U.S. citizen when it is not your birthright? First, you must be a legal, permanent resident of the U.S. for at least five years before you apply. Second, when it comes to the citizenship interview, you must demonstrate working knowledge of the English language, and you must pass a test on United States history and government. You will be asked ten questions, and at least six have to be answered correctly. Some questions are easy, such as the number of stripes or the color of stars on the U.S. flag. Some questions are harder; for example, you have to know the thirteen original states, or you have to be able to name the amendments that address voting rights.
After successfully passing the interview, you have to wait for an invitation to the naturalization ceremony. The ceremony I attended was not quite formal; it was, rather, emotional and cheerfully encouraging. It took place in the friendly Campbell Community Theater, which comfortably held 420 new citizens with their families and friends. Several speakers greeted the new citizens, and the most memorable moment was when one of the speakers presented his grandfather's citizenship certificate issued in 1942. Then the long-awaited moment arrived--everyone rose from their seats, facing the flag with their right hands over their hearts and took the U.S. citizenship oath. I took the oath, and I joined the choir of 420 new citizens singing the "Star Spangled Banner."
A pleasant surprise was waiting for me the next morning when I came into my office. My cubicle was decorated with small flags and flowers, and there was a greeting card signed by all my co-workers and friends. There was more! A big homemade cake with cream cheese and strawberry stripes and fifty blueberry stars was waiting for me in the office kitchen (a special big thanks to Elaine Standifer!). I was amazed and touched by my colleagues' attention and care. Thanks a lot, guys!
I have always felt a sense of family at Stanford: from the time I came to the Stanford emergency room as a volunteer in 2003; completed my medical coding internship in the Anesthesia Department; and, finally, was hired by Stanford Radiology. At Stanford, I have always been surrounded by very nice people who have shaped my professional skills, provided me with valuable advice, and who have been good friends. So, thank you for making this very important day of my life even more memorable and fun!

Elaine Standifer made a "flag" cake to celebrate Galyna's new title as a U.S. citizen.

2007 RSL Retreat at Asilomar

2005 RSL Retreat
At the first Radiological Sciences Laboratory Retreat in 1999, our keynote speaker was Ronald Bracewell, PhD, from the Department of Electrical Engineering at Stanford. Dr. Bracewell received the Institute of Electrical and Electronic Engineers' Heinrich Hertz Medal in 1994 for his pioneering work in antenna aperture synthesis and image reconstruction as applied to radio astronomy and to computer-assisted tomography. Scientists use Bracewell's algorithm, developed for radioastronomical reconstruction from fan-beam scans, to reconstruct tomographic images on commercial CT scanners.

2006 RSL Retreat
Last year, our keynote speaker was Herb Abrams, MD, emeritus professor of radiology at Stanford. He is a world-renowned authority in diagnostic radiology and the impact of ionizing radiation and nuclear weapons. Dr. Abrams was the founding vice president of International Physicians for the Prevention of Nuclear War, which received the 1985 Nobel Peace Prize. At our retreat, he spoke about the biological effects of ionizing radiation. We also attended a workshop on "The Art of Negotiation"; a discussion about the "State of the Lab"; and a "Town Hall Meeting." In addition, each RSL group also developed their own introduction. To view Dan Spielman's group introduction, P.I.M.P. (Person into More Than Protons), please go to http://www.stanford.edu/~pritib/PIMP.wmv. Of course, our retreat would not have been complete without our BBQ and challenging "Jeopardy Game"--complete with categories such as "Name That Patent."
Our keynote speaker this year will be Thorne Lay, PhD, professor in the Earth Sciences Department and director of the Center for Studies of Imaging and Dynamics of the Earth at the University of California, Santa Cruz. He will be speaking on geophysics and geophysical imaging. Our second speaker will be Kelly Skeff, MD, PhD, professor of medicine (general internal medicine) who will discuss various ways to evaluate teaching skills as an introduction to a larger program that his group offers on good teaching practices. Dr. Skeff received the Abraham Flexner Award for Distinguished Service to Medical Education, which was established in 1958 by the Association of American Medical Colleges (AAMC) "to recognize extraordinary individual contributions to medical schools and to the medical education community as a whole."
This year's retreat will be from Wednesday, September 19, through Thursday, September 20, at Asilomar: 800 Asilomar Ave, Pacific Grove, CA (http://www.visitasilomar.com/destination.aspx). After a bag lunch on the beach on Sept. 19th, the retreat will begin at about 1:00 PM, and it will adjourn at about 3:00 PM on the 20th. There is a bonfire a scheduled for Wednesday night at 8:30 PM.
About 45 people attended our first retreat and the largest group we have had so far was in 2005 when the staff, faculty, and students of the Molecular Imaging Program at Stanford (MIPS) joined us, and we totaled 115 people! For 2007, 90 people plan to attend so far.
Identity of Former Exorcist Movie Star, Dr. X, Revealed
Thank you for your patience and your guesses regarding Dr. X's identity in our previous article, "Former Exorcist Movie Star, Dr. X, Tells All"
(http://radiology.stanford.edu/blog/archives/2007/05/former_exorcist.html).
Yes, it is our own Dr. Barton Lane, chief of neuroradiology at the Veterans Administration Hospital in Palo Alto, California, who played the anonymous role of Regan's radiologist in The Exorcist (1973).

Inside Terrorism: the X-ray Project

"The idea for 'Inside Terrorism' began to coalesce in my mind in 2002 as a personal response to terrorism and to my discomfort with the way terrorism has been justified in some circles. This is a documentary of survivors of terrorism," remarked Diane Covert, the artist who created "Inside Terrorism: the X-ray Project." Sponsored by the Radiology Interest Group at Stanford (RIGS) along with various co-sponsors, this exhibit will be showing at the Fairchild Auditorium from September 4-15.
The images of "Inside Terrorism: the X-ray Project" are striking and emotional but, at the same time, are devoid of graphic imagery such as that depicted in Francisco Goya's images of war or Mathew Brady's photographs of the Civil War. We are shown pieces of survivors in CT scans and X-rays with titles like "Smashed Arm," "Damaged Leg," and "Broken Foot." The medium of X-ray and CT, however, makes the horror seem a step removed from the truly gritty and bloody reality of war wounds.
The mundane is made bizarre with images such as "Hex Nut in Brain," "Nail in Arm," and "Watch in Neck." Terrorists often create bombs using common objects, such as hex bolts, nuts, nails, and watches, that were meant for peaceful, utilitarian purposes. These unusual images are the by-products of terrorism's war on civilians.
The images of "Inside Terrorism: the X-ray Project" are displayed on four-sided kiosks, illuminated from the inside, and as standard wall-hung pieces. The CT and X-ray images are of victims of terrorist attacks from the two largest hospitals in Jerusalem, but they could be from anywhere--London, Madrid, New York, Lebanon, etc.
The artist, Diane Covert, described her choice of this unusual medium as follows: "Photography is a way of making an image by drawing with the very light that the objects reflect, so when we look at photographs from the Civil War battlefield of Antietam, we see something very close to the horror of the scenes as they appeared to the photographer. We see records of actual events. Modern medicine draws not with the visible light spectrum used in photography, but with electromagnetic radiation--X-rays and CT scans--and with this we can see inside the human body."
The opening reception for the exhibit is on September 4 from 5:30 PM-7:30 PM. To view the exhibit online, please go to http://www.x-rayproject.org.

Other distinguished speakers included one of the co-developers of the combined PET/CT scanner, David W. Townsend, PhD, professor of medicine and radiology as well as director of the Cancer Imaging and Tracer Development Research Program at the University of Tennessee in Knoxville. Along with Dr. Ronald Nutt, president of CPS Innovations, Dr. Townsend developed the combined PET/CT scanner, which was named by Time magazine as the medical invention of the year 2000. Also among the conference presenters were Stanford scientists Craig Levin, PhD, associate professor of radiology (nuclear medicine), and Christopher Contag, PhD, associate professor of pediatrics (neonatology), associate professor of microbiology & immunology, and associate professor of radiology.

Drs. Townsend, Levin, and Contag
In his closing remarks, Dr. Gambhir noted the rapid development and immense promise of molecular imaging to provide tools for the far earlier detection of cancer and the assessment of therapy response. Specifically, he praised the interesting results in hyperpolarized MRI; the improvements in imaging agents; the importance of nanotechnology; and the increase in signal amplification. His closing remarks also addressed a myriad of new breakthroughs made possible by molecular imaging such as an increased understanding of brain biology, particularly in the areas of addiction and Alzheimer's disease.
Simultaneously, Dr. Gambhir stressed that the field needs molecular imaging and "morphologic and anatomical imaging to advance" together. A main theme of his closing remarks and the conference was the importance of unifying across multiple modalities and disciplines to encourage drug development; consortium activities for sharing imaging biomarkers; and clinical translation. "We need to start unifying principles even in the complex environment of tumor biology," Dr. Gambhir asserted, "by looking at the relationships between components of a system."
Dr. Norbert Pelc's Research Featured in AuntMinnie.com

Our Department's innovative research on volumetric inverse geometry CT (IGCT), directed by Dr. Pelc, ScD, was recently featured in an AuntMinnie.com article, "Inverse-Geometry CT Project Promises Higher Image Quality, Fewer Artifacts," by Eric Barnes (http://www.auntminnie.com/index.asp?Sec=sup&Sub=cto&Pag=dis&ItemId=76261).
Current multi-detector-row CT systems are unable to acquire volumes thicker than 4 cm in a single rotation, which impedes the imaging of larger organs, such as the heart, in a single rotation. The extension of this technology to image thick volumes has fundamental limitations. By using an array of sources, Dr. Pelc's IGCT research allows thicker volumes to be imaged faster with higher resolution and no cone-beam artifacts, which promises to improve the imaging of larger organs and to benefit difficult applications such as cardiac CT angiography and perfusion studies. Dr. Pelc described his results as "promising": "It's a technology that can be scaled to an arbitrary slab thickness; does not have conebeam artifacts; can deliver isotropic and homogenous spatial resolution across a higher volume; and offers excellent dose efficiency, partly as a result of the virtual bow tie." For more detailed reading on Dr. Pelc's research, please see "Inverse-Geometry Volumetric CT System with Multiple Detector Arrays for Wide Field-of-View Imaging" in Medical Physics (June 2007;34(6):2133-2142)
(available online at http://scitation.aip.org/getpdf/servlet/GetPDFServlet?filetype=pdf&id=MPHYA6000034000006002133000001&idtype=cvips).
The AuntMinnie.com article featuring Dr. Pelc's IGCT research is based on his June 13, 2007 presentation, "Volumetric Inverse Geometry CT (IGCT) with a Large Field-of-View," from the 9th Annual International Symposium on Multidetector-Row CT (MDCT) held at the Hyatt Regency in San Francisco, CA. Dr. Pelc was one of more than 64 world-renowned speakers featured at the MDCT, which offered over 180 lectures on topics such as "Technology: Present and Future"; "Contrast Medium Delivery and Risk Management"; "Pediatrics"; and "Cardiac PET/CT and Non-Coronary Applications."
The conference also included a special seminar on cardiovascular imaging; a hands-on workstation training; extensive equipment exhibits; and the 5th annual workstation face-off. During the face-off, physician-operators navigated the same five clinical datasets using different workstations to compare the capabilities, image quality, and workflow strategies of the workstations.

The Canary Foundation, a nonprofit organization that funds research in early cancer detection, has donated $7.5 million to Stanford University to fund early cancer detection. Of this total, $1.5 million will go to the Stanford Cancer Center, which has recently received a National Cancer Institute designation. The Department of Radiology will match the remaining $6 million of the Canary Foundation pledge with $4 million, resulting in the allocation of $10 million to establish a Center of Excellence for Cancer Early Detection. Headed by Sanjiv Sam Gambhir, MD, PhD, professor of radiology as well as bioengineering and director of the Molecular Imaging Program at Stanford (MIPS), the Center will advance molecular diagnostics by emphasizing molecular imaging to detect cancer at its earliest and most treatable stage.
Our Chairman, Gary M. Glazer, praised the alliance between our Department and the Canary Foundation: "Stanford's Radiology Department has played a leading role in advancing the revolution in medical imaging, which has transformed patient care over the past several decades. The newly developing field of cellular and molecular imaging has immense promise for providing tools for the far earlier detection of cancer and the assessment of response to therapy than existing methods. We are delighted that the Canary Foundation has recognized this potential and the strengths of Stanford by generously contributing to create this Center of Excellence."
The money for the Center will be allocated by a board consisting of Dr. Gary M. Glazer; Dr. Sam Gambhir; Dr. Beverly Mitchell, deputy director of Stanford's Cancer Center; and Donald Listwin, founder and CEO of the Canary Foundation (http://www.canaryfoundation.org). Dr. Gambhir is one of the researchers who will receive funds from the Canary Foundation's pledge. His work focuses on merging advances in molecular biology with those in biomedical imaging to revolutionize the diagnosis and management of disease and enable fundamental studies of cancer biology in living subjects (http://cancer.stanford.edu/features/research_news/Canary-Gift.html).
By making a pledge, the Canary Foundation has recognized the potential of developing new tools for the early detection of cancer and acknowledged the strengths of our faculty to make this a reality. The broad initiatives of the Center of Excellence offer great synergies with existing efforts across our Department and the School of Medicine. This remarkable opportunity will enable our faculty to pursue promising lines of work in early cancer detection.

Lifetime Achievement Award: Dr. William Northway, Jr

(Image courtesy of Mark Riesenberger)
During his first year as an assistant professor of Stanford Radiology in 1964, Dr. William Northway, Jr, was captivated by what appeared to be multiple cysts in the chest X-rays of premature infants in severe respiratory failure who had been treated with mechanical ventilation and high oxygen concentrations. With his curiosity piqued, he began his research. By 1967, Dr. Northway had made a startling discovery: the high levels of oxygen used to treat respiratory failure in newborn premature infants were causing a new chronic lung disease, which he called bronchopulmonary dysplasia (BPD). His pioneering work dramatically changed the treatment of respiratory failure in newborn premature infants.
Dr. Northway is a Stanford legacy, who was born and raised in Palo Alto. His father served as the chair of physical medicine and rehabilitation at Stanford, and his mother was a nurse at Stanford-Lane Hospital before her marriage. He attended Palo Alto High School and Stanford University for his undergraduate and medical degrees. At Stanford, he met Drs. Henry Jones and Henry Kaplan and decided to become a radiologist. After medical school, Dr. Northway headed to the East Coast to complete an internship in internal medicine at the New York Hospital (Cornell University). He returned to Stanford in 1958 to begin his residency in radiology and encountered Dr. Robert Evans, the first pediatric radiologist at Stanford, and Dr. Herb Abrams. Both were critical to his interest in becoming an academic pediatric radiologist.
After finishing his residency in 1961, he enlisted in the air force and was stationed at Keesler Air Force Base Hospital in Biloxi, Mississippi, as the assistant director of the Department of Radiology from 1961 to 1963: "I spent two years in the United States Air Force as a captain and as one of two radiologists at a 500-bed hospital." At Keesler, he met and married his wife, Linda. In 1963, Dr. Northway obtained a fellowship at the Hopital des Enfants-Maladies in Paris, France, with the assistance of Dr. Robert Evans and Professor Jacques Lefevre, the leading French pediatric radiologist at the Hopital des Enfants-Maladies. Through Dr. Kaplan, he also secured a James Picker Foundation Fellowship for support.
Working at the Hopital des Enfants-Maladies was an enlightening experience, according to Dr. Northway: "The hospital had about 500 beds at the time, and it was repudiated to be the largest and oldest children's hospital in the world. Many of my patients had been flown in from the French colonies in Africa, so I saw things that you wouldn't see in the United States, like scurvy, which is caused by vitamin C deficiency; rickets, which is caused by vitamin D deficiency; and tuberculosis (TB) of the spine and other areas. They also had a large ward of patients with congenital bone dysplasias that no one had categorized yet."
He returned to Stanford in 1964 as an instructor in radiology and held a faculty position at Stanford throughout the rest of his 34-year career. Over the years, Dr. Northway has seen a multitude of changes. When he began in the Stanford Department of Radiology, children were not separated from adult patients for radiologic purposes. Also, radiotherapy, nuclear medicine, and diagnostic radiology were still one department when he was the director of the Division of Diagnostic Radiology from 1976 to 1981.
Most memorable were the technological advances. In the 1970s, CT and ultrasound technologies were primitive, but developing, Dr. Northway recalled: "We were just starting to have ultrasound and CT at that time. Initially, Dr. Zatz, who was developing the ultrasound technique, immersed the body part to be examined in water, and he reached in the water bath with the ultrasound equipment to make the images."
Teaching has changed as well. When Dr. Northway presented at grand rounds early in his career, he and his colleagues always presented with X-rays, lab results, and the patient, who is rarely involved with grand rounds today because of privacy issues. These changes in teaching have made it exciting but challenging. "Someone said once that by the time you have been out of medical school for 10 years only 10% of what you learned will still be in effect. When I was in medical school, they hadn't discovered DNA! The fun of teaching is passing on new knowledge," Dr. Northway asserted. Even amidst all the revolutionary changes, Dr. Northway had time to complete his research, in part, because the chair, Henry Kaplan, had established a policy that allowed each new tenure track faculty member to spend two days a week on research and three days on clinical care.
This protected research time allowed Dr. Northway to make a discovery that would permanently alter the treatment of premature infants with respiratory failure or hyaline membrane disease/respiratory distress syndrome (RDS). When he arrived at Stanford in 1964, pediatricians were just beginning to use very high levels of oxygen to treat premature infants with RDS. When a colleague asked him to look at a series of chest X-rays from treated premature infants, Dr. Northway was puzzled by the appearance of cystic changes in the lungs. After ruling out staphylococcus pneumonia, he examined all the infant charts, nursing notes, and pathology and concluded that the lung changes were related to pulmonary oxygen toxicity.
Dr. Northway's findings were published in a seminal article entitled, "Pulmonary Disease Following Respirator Therapy of Hyaline Membrane Disease (Bronchopulmonary Dsyplasia)," in The New England Journal of Medicine (1967 Feb 16;276(7):357-68). His many research studies on BPD helped advance the therapy of premature infants with respiratory failure by promoting the lowering of therapeutic oxygen concentrations. This, along with lower ventilator pressures and other advances in neonatology, significantly decreased the mortality rate for premature infants with respiratory failure.
In 1998, Dr. Northway retired from a 34-year academic career. During the same year, he was selected as the "Pioneer Session Honoree" by the Society for Pediatric Radiology (SPR) for his important contributions to the development of pediatric radiology. In 2003, he was awarded the SPR Gold Medal. In honor of his distinguished career, Dr. Northway also received the 2005 J.E. Wallace Sterling Lifetime Alumni Achievement Award, which is bestowed annually by the Stanford Medical Alumni Association in recognition of "exceptional lifetime achievement" in medicine. He continues to serve our Department as an active emeritus professor of radiology and pediatrics.
American Association of Physicists in Medicine (AAPM) Praises Medical Physics at Stanford
During their visit to Stanford on January 19, 2007, members of the AAPM Science Council were extremely complimentary about medical physics at Stanford after touring the Departments of Radiology and Radiation Oncology. AAMP Science Council Chair, John Boone, PhD, described seeing "one impressive lab after another, from MRI to x-ray CT physics, radiation therapy to molecular imaging, image processing to small animal imaging." By the end of the tour, he concluded that "excellence in medical physics research was evident at a scale that is perhaps matched by only a handful of universities in North America."
More than 5,000 medical physicists belong to the AAPM, a scientific, educational, and professional organization that promotes the application of physics to medicine and biology. Composed of 19 members, the AAMP Science Council acts as a clearinghouse for scientific inquiries and makes scientific policy recommendations to the AAMP Board. The Science Council meets on a regular basis and, once a year this meeting is held at a member's institution so that the Council can learn about the science being done by AAPM members. For more information on the AAMP, please visit http://www.aapm.org/org/default.asp.
The chair of our Department, Gary M. Glazer, MD, would like to thank Norbert Pelc, ScD, who is also a member of the AAMP Science Council, and the rest of the Stanford faculty and staff who helped coordinate the Science Council's tour of Stanford facilities: Chris Contag, PhD; David Dick, PhD; Sam Gambhir, MD, PhD; Arun Ganguly, PhD; Gary Glover, PhD; Paul Keall, PhD; Craig Levin, PhD; Sandy Napel, PhD; and Lei Xing, PhD.

Awards and Honors: May 22, 2007

Luke Higgins, PhD, first-year medical student, has been awarded a Society of Interventional Radiology (SIR) Foundation Medical Student Research Grant. Through this grant, SIR encourages medical students to engage in cutting-edge research in interventional radiology that will likely translate to improved patient care. Funding criteria includes scientific merit, innovative quality of the research proposal, and relevance to interventional radiology. Dr. Higgins earned his PhD in biological chemistry from MIT and is now working with Lawrence "Rusty" Hofmann, MD, who is investigating the delivery of autologous adipose-derived multipotential stromal cells (ASCs) to treat peripheral arterial disease. Under Dr. Hofmann's mentorship, Dr. Higgins will be analyzing the capacity of human and rabbit MR-labeled ASCs to differentiate and express arteriogenic factors relative to unlabeled cells and will be comparing these expression levels to cells under stressed conditions.
Former Exorcist Movie Star, Dr. X, Tells All

Did you know that one of our very own physicians, Dr. X, is a former movie star? Dr. X had an important, although anonymous, role in The Exorcist (1973). His/her identity will also remain anonymous until readers identify him or her from the script that follows or from the movie clips we will include in the next Exorcist posting in the coming weeks.
This movie was nominated for ten Academy Awards in 1973 and won two, the Academy Award for Sound and the Academy Award for Writing Adapted Screenplay. It also won four Golden Globes, including the award for the Best Picture-Drama for the year 1974. The Exorcist was based on the novel by William Peter Blatty, Exorcist (1971), which spent 55 weeks on the New York Times Bestseller List. Blatty earned an Oscar and a Golden Globe for the screenplay adaptation of his book.
The Exorcist was directed by William Friedkin and starred Linda Blair as Regan MacNeil (the possessed girl); Ellen Burstyn as Chris MacNeil (the mother of the possessed girl); Jason Miller as Father Damien Karras (a priest and psychiatrist); and Max von Sydow as Father Lankester Merrin (an older priest adept at exorcisms). The theme music is a part of the composition called Tubular Bells by Mike Oldfield. The horror begins when a visiting actress in Washington, D.C., Chris MacNeil, notices drastic changes in the behavior of her 12-year-old daughter, Regan, who is abnormally strong and can levitate her whole body.
To find the source of her daughter's strange behavior, Chris takes Regan for an electroencephalogram (EEG), angiogram (performed by Dr. X), and pneumoencephalogram. When these tests show no abnormalities, Chris and Regan are sent to Father Karras, who is also a psychiatrist. Convinced that Regan is possessed, Father Karras and a second priest experienced with exorcisms, Father Lankester Merrin, try to exorcise the spirit from Regan before she dies.
Dr. X became involved in the filming of The Exorcist while completing his/her second year of a neuroradiology fellowship at New York University (NYU) Medical Center. As the senior fellow, s/he did lots of procedures such as angiograms, pneumoencephalograms, myelograms, etc. One day in the fall of 1972, as Dr. X was performing a carotid angiogram, his/her chairman, Dr. Norman Chase, came by to observe, with a stranger in tow. This was not unusual because important visitors were occasionally allowed to visit and evaluate their procedures, equipment, etc. NYU Medical Center was one of the leading neuroradiology centers in New York. Later that day, Dr. Chase told Dr. X that they would be making a movie, and asked if s/he would be interested in participating. Dr. X said "Yes sure," and promptly forgot about the incident.
Several months later in January of 1973, a whole film crew descended upon the NYU Radiology Department for two weekends. The film crew closed off part of the Department, utilized their angiography and pneumoencephalography suites, and proceeded to set up and film the (now famous) carotid angiography and pneumoencephalography sequences. To read about these scenes, please see the excerpt from The Exorcist script below.
Dr. X's participation was for two full days on the first weekend. According to Dr. X, "The other people in the angiogram scene with me are not actors; they are the radiologic technologist and nurse who actually worked with me every day. We duplicated exactly what we did for any carotid angiogram; I am most proud of the fact that even now, 30-plus year later, it holds up as a very realistic demonstration of the procedure." Dr. X claims that s/he was given the part because the chairman liked him/her: "He [the chairman] also is the only one who got film credits. His name appears at the end, not mine. (That's when I first learned that the radiology chairman always takes the credit!) :)" Dr. X's chairman, Dr. Norman Chase, is listed under the "Other Crew" section in the credits as follows: "Norman E. Chase. M.D. . . . . technical advisor."
Although the film was a huge international hit in 1973 and became the highest-grossing film of the year (see Wikipedia, http://en.wikipedia.org/wiki/The_Exorcist_%28film%29), Dr. X did not receive the lion's share of the profits. For his/her participation in the film, Dr. X was paid $200, which was a lot of money for a struggling fellow back in 1973! So far, The Exorcist has a total gross of $402,500,000 worldwide; if adjusted for inflation, this would be the top-grossing R-rated film of all time.
What were his/her fellows actors like? "As for the actors: I spent two solid days with Linda Blair who was an unknown thirteen-year old at the time; her mother was there too (actually has a bit part in the movie). Linda was very cooperative with all of us working on her. I remember she liked horses. I was able to meet the actress who plays the mother, Ellen Burstyn, too. The director, William Friedkin, was constantly directing us every step; he was incredibly professional and detail-oriented. So was the cinematographer, Owen Roizman, and the make-up guy who devised, with our help, the blood-spurting part of the sequence. I think he got on Oscar nomination for his work in the movie (think: pea soup and rotating heads!)."
When released in 1973, some theatre patrons reportedly screamed and fainted while viewing the film, requiring paramedics to be called to theaters. Theaters allegedly provided "Exorcist barf bags" (see http://www.findarticles.com/p/articles/mi_qn4158/is_20061104/ai_n16829894).

Dr. X's acting contributed to the nausea: "Again, I kind of forgot about the thing, figuring this was an interesting episode but one that would never see the light of day. Much to my surprise, in December of that year [1973], The Exorcist movie was released with tremendous impact. It was considered shocking, over-the-top, scary as the dickens, and the part that most sickened people was the angiogram sequence I had done!!! Go figure."
Other trivia buffs (see http://www.thefleshfarm.com/exorcist/exorcist1.htm) allege that due to death threats against Linda Blair, Warner Brothers had bodyguards protecting her for six months after the film's release. Some trivia facts websites (see http://imdb.com/title/tt0070047/trivia) claim that one filmgoer, who saw the movie in 1974 during its original release, fainted and broke his jaw on the seat in front of him. Claiming that the use of subliminal imagery in the film had caused him to pass out, he sued Warner Brothers and the filmmakers. The studio settled out of court for an undisclosed sum. Another unsuspecting moviegoer was Dr. X's identical twin sibling, who is also a physician. Dr. X forgot to tell his/her sibling about his/her role in the movie. When Dr. X's sibling and his/her significant other saw the movie, Dr. X claims that "they both freaked out!!!"
Today, Dr. X is comfortable talking about his/her acting debut, but that was not always the case: "For many years I never volunteered to people that I was in the movie. My career as an academic neuroradiologist was beginning, and I thought this would only be damaging to it, especially if one of my patients saw the scene. Now that I'm an old has-been, I admit to it if someone asks. But it's still not in my CV!"
While s/he hasn't had any further movie offers, Dr. X did get to meet Linda Blair many years later: "I did get to meet Linda Blair 25 years later as she was touring the country, promoting the 25th anniversary Exorcist DVD. So I decided to go see her at a bookstore. She looked great, I thought, and was as nice as could be, although I don't think she really remembered me. But she signed a cool Exorcist poster for me, with the words 'To Dr. X: what you did to my neck was a real head-spinning experience!' (Corny, but I like it)."
Can you name Dr. X?
CAST FOR THE ANGIOGRAM SCENE FROM THE EXORCIST:
Doctor: Dr. X
Regan MacNeil (Linda Blair): the possessed girl
Chris MacNeil (Ellen Burstyn): Regan's mother
Male Radiologic Technologist (RT)
Prior to the following scene, Regan's mother, Chris MacNeil, has consulted with a neurologist and a pediatric neurologist about her daughter's erratic behavior. They have recommended that Mrs. MacNeil have her daughter examined for a possible lesion in the temporal lobe of her brain. So, Mrs. MacNeil takes her daughter to Dr. X for an angiogram.
INTERIOR OF THE HOSPITAL, ANGIOGRAPHY SUITE, DAYTIME
[Regan is being wheeled on a bed to the angiography table. They place the bed next to the table and pull the siderails down.]
MALE RADIOLOGIC TECHNOLOGIST (RT): Regan, could you sit up and scoot over here?
[Regan does so, and she lies back on the angiography table. The RT pushes a button and the table begins to move forward.]
MALE RT: Regan, I'm just gonna move you down to the table okay?
[The table comes to a halt.]
MALE RT: Just for a short time.
[The RT and the female nurse loosen Regan's gown around the neck to prep her for the doctor. They place monitors on her arms.]
MALE RT: Very sticky.
[The doctor approaches Regan with a cup of Betadine and puts a sponge into the cup.]
DOCTOR: Now Regan, you're going to feel something, a little bit cold and wet.
[S/he dabs the sponge onto her neck making it a light brown color. The doctor then picks up a hypodermic needle and syringe and moves toward her. We see Chris and Dr. Klein, a pediatric neurologist, in the viewing room.]

DOCTOR: Okay, now you're gonna feel a little stick here. Don't move.
[The doctor inserts the needle into Regan's neck and injects local anesthetic.]
DOCTOR: Good.
[S/he then picks up a carotid angiogram needle and moves toward her.]

DOCTOR: Okay, you're gonna feel some pressure here, now don't move.


[The doctor places the carotid needle into her neck. Regan is quietly yelping in pain, and Chris is in pain watching her daughter suffer.

The doctor takes the stylet from the needle, which squirts pulsating blood, and fastens a tube onto the needle's hub. We see the blood rush from Regan's neck through the tube. The male RT then tapes Regan's chin down to prevent her from moving. The RT then wheels in a huge machine (the film changer), with parts on either side of Regan's head and a piece above.

The lights fade out, and all we can see is Regan's face illuminated by this huge machine above her.]
DOCTOR: Hook up.
[We see a finger flip a switch and the machine comes to life. Another RT in the view room pushes another button and the machine lets off several loud bangs. In the angiography room, we can see Regan crying.]
END OF ANGIOGRAM SCENE

The X-ray films from Regan's cerebral angiogram are normal. The doctors recommend that Regan have a pneumoencephalogram in a last attempt to locate the suspected lesion.


The results from the pneumoencephalogram are also negative.

Lucile Packard Pediatric Radiology Participation at the Society for Pediatric Radiology

Established in 1958 with the goal of improving pediatric health care through medical imaging, the Society for Pediatric Radiology (SPR) recently held its 50th annual meeting in Miami, Florida. This is the major academic society and annual meeting for pediatric radiologists. This year the Society also put together a specific program to support their junior pediatric radiologists, which included a luncheon, small group lectures focusing on clinical and professional issues, and a social outing at one of Miami Beach's popular spots.
I attended the conference with a large contingent of pediatric radiology faculty from Lucile Packard Children's Hospital including Drs. Richard Barth, Frandics Chan, Patrick Barnes, Erika Rubesova, and Hans Ringertz as well as several current and former fellows: Drs. Shreyas Vasanawala, Michael Krasnokutsky, and Dorothy Gilbertson-Dahdal. Dr. Chan and I participated in the postgraduate course and gave talks entitled "Pediatric Cardiovascular CTA: Applications" and "Cardiac Manifestations of Systemic Disease in Children," respectively. I also presented a paper entitled "Imaging Pulmonary Venous Obstruction" and was the senior author on a paper entitled "Coronary Artery CTA in Children," presented by Dr. Alexander Towbin from the Children's Hospital of Pittsburgh.
In addition, Dr. Barnes and I presented pediatric radiology workshop sessions in neuroradiology and pediatric chest, respectively. Dr. Krasnokutsky presented two papers on which Dr. Barnes was the coauthor: "Cerebral Venous Thrombosis: A Mimic of Non-Accidental Injury" and "Spinal Cord Injury without Radiographic Abnormality (SCIWORA)--A Mimic of Non-Accidental Injury (NAI)."
Our faculty and fellows also presented or co-authored multiple other scientific papers at the Society for Pediatric Radiology. Dr. Dorothy Gilbertson-Dahdal presented "Three Newborns with Malrotation and Midgut Volvulus Mimicking Duodenal Atresia on Plain Film," which was co-authored by Drs. Laura Varich and Richard Barth. Dr. Shreyas Vasanawala presented "MR Voiding Cystography, Evaluation of Vesicoureteral Reflux" while Dr. Erika Rubesova delivered a paper entitled "Third Trimester Fetal MRI: Can We Reduce Post-Natal Imaging." Both papers were co-authored by Dr. Richard Barth.
Overall, there was a great representation of our pediatric radiology faculty at this important pediatric scientific meeting, and they are to be congratulated.

My 33 Years of Service at the Digital Image Library

By Carla Crivello, Digital Image Librarian
(Image courtesy of Mark Riesenberger)
It was a hot October day in 1973 when I started working in what is now called the Digital Image Library of the Stanford Radiology Department. I knew nothing about X-rays because I had been working for four years in the Outpatient Medical Records Department at Silas B. Hayes Army Hospital at Fort Ord, California. The Radiology Department was much smaller than it is today. The whole Department was located in what had been "Radiology South." The building where Radiology North is today had not been built.
There was no ultrasound, computed tomography, magnetic resonance imaging, or mammography. I had to learn about the different reading rooms where each kind of X-ray was read. There was also no computer system of any kind. The reception area contained a large, rotating machine called a rand where index cards on each patient were kept in alpha order. One of my main jobs was providing old comparison X-rays along with the new X-rays for the radiologist to read. This has been one of my main job duties throughout my career. About 10 years later, Radiology built its own computer system; in 1991, this system was upgraded to a system that allowed the film librarians to use a bar code to check X-ray films in and out of the library, which was also part of my job duties.
No analog X-rays are taken anymore. All studies are now digital and can be viewed by the radiologist on a Picture Archiving and Communications System (PACS) workstation along with older digital X-rays that were taken in 2003 or later. The new PACS digital system makes it much easier for the radiologists to read their studies. I routinely sent the paperwork for the new chest X-rays to the reading room to alert the radiologist to read that X-ray from the worklist on PACS. If I needed to release an X-ray to a patient, doctor, or clinic, I would print a hard copy or burn a CD of the X-ray using PACS.
My last day of work on April 3, 2007, was a fun day! My son, Chris, surprised me by arriving at my workplace with balloons and a large box of bagels for everyone in the Digital Image Library! My fellow librarians held a potluck for me that included food from the Olive Garden, and it sure was good! In addition, the Radiology Department gave me a party with a luscious strawberry cake, refreshments, and a beautiful crystal piece to go in my collection. It was wonderful to see so many people there to wish me well. Some of my former colleagues whom I had worked with many years ago attended my party as well. Several people gave very nice speeches while others expressed their kindness with lovely cards and gifts.
Thanks to the fine leadership of Deborah Williams, digital image library supervisor, and Tori Shannon, business systems analyst, my 33 years of working in the Digital Image Library has been a stimulating and rewarding experience! I have enjoyed working with my fellow librarians, X-ray technologists, schedulers, doctors, and everyone else I have interacted with over the years. I will miss you all.
My husband, Horace, is already retired, so we will be spending quality time together. We will complete projects around our house and yard, watch DVD movies, catch up on our reading, and just relax. Stanford Hospital has been a great place to work! I will always have fond memories, and I will come back to visit often.
Thank you!

Lifetime Achievement Award: Dr. Matilde Nino-Murcia

(Image courtesy of Mark Riesenberger)
In November of 2006, Dr. Matilde Nino-Murcia received the Inspirational Immigrant Professional of the Year (IIPY) Award from Upwardly Global at the Commonwealth Club of California in San Francisco. Founded in 1999, Upwardly Global is a nonprofit organization that helps highly qualified immigrant professionals, who are also permanent residents, write resumes, refine interviewing skills, and develop professional networks. Many of the immigrants who use the services of Upwardly Global were doctors, lawyers, and engineers in their former country. However, most have to work as waiters, taxi drivers, etc. until they can get a U.S. license or degree because their licenses and degrees are often not valid in the U.S. As a volunteer and mentor, Dr. Nino-Murcia works with immigrant professionals interested in medicine: "I review their resumes and talk to them about the opportunities that exist here and guide them on how to validate their medical licenses."
Because of her dedication and commitment as a volunteer and a mentor, Dr. Nino-Murcia was one of many nominees selected nationwide for the IIPY Award: "Being the recipient of this award meant the world to me because it is a recognition of what I've tried to do throughout all these years: help others to succeed. It is also a recognition of my mentors, Drs. Gerald Friedland and Brooke Jeffrey, who have guided and supported me throughout my academic career here at Stanford. As the saying goes, when you walk through the jungle, you need to do what you can to clear a path through the trees so that others can follow. It is this process that I have found to be the most rewarding in my career."
The challenges she has faced as an immigrant are not the only obstacles she has had to overcome in her lifetime. She was born in a very small town about 200 miles from Bogota, the capital of Colombia. While her mother was not able to give her children wealth, she was able to give them an education. As a young girl, Dr. Nino-Murcia originally wanted to be a nurse, but her mother encouraged her to become a physician because she knew her daughter could succeed. And she did. Graduating from high school at sixteen, Dr. Nino-Murcia went on to medical school at the National University of Colombia in Bogota where she was one of only seven women in a class of 90 students. By the time she graduated from the National University of Colombia School of Medicine, she ranked second in her graduating class.
After their internships and one year of service, she and her husband, a medical school classmate, decided to immigrate to the United States. Dr. Nino-Murcia was a twenty-six year old Colombian medical school graduate, wife, and mom when she first arrived in the United States in 1975. "We had professors who had trained in the United States. They were our role models in medical school," she explained to me. "We came here to get better training and preparation to bring back to our medical school in Colombia. However, we stayed, in part, because the political situation in Colombia had become very unstable due to guerrillas and drug trafficking."
Today, the United States feels like her home, but it was not always that way. Learning a new language and culture were challenging, but having someone to learn it with helped: "When I came here, my older daughter was about two and half years old, so I used watch Sesame Street with her--Big Bird, Bert, Ernie, and the Cookie Monster were some of the most effective language instructors of my daughter and me. You can learn amazing things when you must do so to survive, and when your teachers can make you laugh while learning."
Even after she proved her proficiency in English by passing the Test of English as a Foreign Language (TOEFL), Dr. Nino-Murcia was devastated to receive only rejections to the fifty letters she sent out to teaching hospitals along the eastern seaboard who told her, "This program does not accept FMGs [foreign medical graduates]." Finally, Dr. Nino-Murcia picked up the phone and called four local hospitals. The fourth hospital was Thomas Jefferson University Hospital in Philadelphia. They had an opening and wanted her to start that week.
Becoming a medical resident in the United States was a major success, but it is not among Dr. Nino-Murcia's proudest achievements. These are personal. Her most significant accomplishment is her daughters. Beaming, she told me, "I am so proud of them. They both went to Stanford. The older one majored in English literature and then went to Berkeley and got her master's in education. She's a high school teacher. My younger one got her undergraduate and master's in earth systems. She works in San Francisco as a consultant for mining companies in South America and Africa, developing strategies to preserve the environment and well-being of the people impacted by the mining industry. They are both very passionate about their work and giving back to the community."
Her second greatest achievement is being a professor in the Stanford Department of Radiology: "It is truly a privilege to be a member of such a great Radiology Department. The people in our Department are very talented, accomplished, and very friendly. It is great to work at a place where you are constantly learning and surrounded by people you look up to." Dr. Nino-Murcia has been at the VA since 1984, where she specializes in applying multidetector computerized tomography technology for the diagnosis, classification, and staging of pancreatic cancer; using positron-emission tomography to evaluate genitourinary tumors; and evaluating gastrointestinal motility disorders in patients with spinal cord injuries.
As she acknowledged in her acceptance speech for the IPPY award, being a foreigner has its advantages: "My background growing up in a rural community outside of the United States and my struggles to learn English and understand a new culture all gave me awesome problem-solving skills, as well as a heightened appreciation for those who mentored me and a strong belief that I should give back to those who follow."
And throughout her professional career, she has given back. Dr. Nino-Murcia has mentored college students interested in health careers, and she continues to serve disadvantaged students by actively participating in the Stanford Health Careers Opportunity Program; the Clinical Shadow Experience for Minority and Disadvantaged College Students; and the School of Medicine Minority Orientation Weekend.

3D Laboratory Celebrates Ten Years of Service
By Laura J. Pierce, MPA, RT (CT)

3D lab group photo taken March 2007 (image courtesy of Mark Riesenberger). First row (L to R): Sandy Napel, PhD, 3D lab Co-Director; Laura Pierce, MPA, RT (CT); Geoffrey Rubin, MD, 3D lab Co-Director; Second row (L to R): Kala Raman, MS; Keshni Kumar, CRT; Linda Novello, RT (MRI); Third row (L to R): Noe Hinojosa, RT (CT); William Johnsen, RT (CV) (RCIS); Lakeesha Winston; and Marc Sofilos, RT.
In September 2006, the Stanford 3D Medical Imaging Laboratory celebrated a decade of service to the Stanford Medical community. When the 3D Medical Imaging Laboratory was established in 1996, we had 300 square feet of space in the basement of the Grant building, occupied by one 3D imaging technologist (Laura Logan), and seven engineering students, postdoctoral fellows, and clinical researchers. The average monthly 3D volume was 64 examinations. Today, we have 1300 square feet of space in our two labs and six 3D imaging technologists: Laura Pierce, 3D Lab Manager (formerly Laura Logan); Marc Sofilos; Linda Novello; Keshni Kumar; William Johnsen; and our newest technologist, Noe Hinojosa. We also employ a full-time administrative assistant, Lakeesha Winston, and a software engineer, Kala Raman. The lab retains an annual average of twelve engineering graduate students and postdoctoral fellows as well as two clinical MD researchers. Our average monthly 3D volume has increased more than ten fold to 750 examinations.
In 1996, Co-Directors Geoffrey Rubin, MD, and Sandy Napel, PhD, created the 3D laboratory with the mission of developing and applying innovative techniques for the efficient analysis and display of medical imaging data through interdisciplinary collaboration. Ten years later, this mission continues to drive our operations and infuses our clinical, educational, and research goals. Clinically, our objective is to deliver 3D imaging advances as rapidly as possible following validation by the Stanford and worldwide healthcare communities. The 3D laboratory operates simultaneously in two locations: the first floor of the Lucas Center in P170 and the third floor of the James H. Clark Center in room S344 (next door to Peet's Coffee). We have processed over 44,000 examinations since our inception in 1996 (see figure 1). The lab provides 3D services for nearly every clinical department at the Stanford Medical Center. Ninety percent of our referrals are from CT examinations; the remainder is from MRI studies. With rapid advances in CT and MRI scanning over the past ten years, our 3D examinations now provide a larger range of coverage with better temporal and spatial resolution (see images 1, 2, and 3).
Our educational aim is to disseminate knowledge and duplicate our 3D services at other institutions by providing training for local and international physicians and technologists in the latest developments in 3D imaging. The 3D lab is attended by a rotation of Stanford Radiology fellows, residents, and medical students who are acquiring skills in 3D interpretation, which will be useful in their future clinical practices. In response to the external demand for 3D imaging training, the 3D lab has sponsored an increasing number of domestic and international visiting radiologists and technologists who have sought training through our 3D clinical fellowship program. We average three to five visiting fellows per month from a combination of local, national, and international hospitals and medical centers.
To fulfill our research goals, we are developing new approaches to the exploration and analysis of diagnostic images that will create new and more cost-effective diagnostic approaches as well as new techniques for the design and planning of therapy. The students and fellows we educate also make important contributions to our research by developing new image processing techniques. Professor Sandy Napel is the advisor of several PhD candidates and, occasionally, postdoctoral fellows. Each does research on a challenging area of image processing, such as the computer-aided detection of cancerous polyps on CT colon studies.
As we enter our second decade, the 3D Medical Imaging Lab continues to function as an international leader in clinical care, teaching, and research in medical imaging analysis. The confluence of talented medical and engineering expertise in our Department as well as the most up-to-date equipment has been a consistent source of innovative developments in our diagnostic and treatment planning approaches.

The Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR) and the National Cancer Institute (NCI) Annual Site Visit, March 30, 2007

Over 75 visitors from a variety of universities, foundations, and industries attended the CCNE-TR/NCI annual site visit organized by Sanjiv Sam Gambhir, MD, PhD, professor of radiology and bioengineering; director of the Molecular Imaging Program at Stanford; chief of the Nuclear Medicine Division; and principal investigator of the CCNE-TR. The annual CCNE-TR/NCI site visit provides an opportunity for the NCI to review and experience CCNE-TR research and enables the scientists involved in the multiple cores of the CCNE-TR to convene in one meeting and share their scientific progress.

Dean Philip Pizzo, MD, and Beverly Mitchell, MD, director of the Cancer Center, were among the 20 speakers presenting in the Clark Center. The site visit also included presentations featuring such topics as the proteomic identification of markers of therapeutic response in prostate cancer; the biological modification of quantum dots for in vivo targeting; and mouse cancer models for integrated tissue/serum proteomics and molecular imaging.
Like scientists at the National Cancer Institute (NCI), researchers at the CCNE-TR are convinced that nanotechnology will make a significant impact on cancer diagnosis and management in potentially revolutionary ways. The goal of the CCNE-TR is to develop and validate nanotechnology so that it will be possible to predict which patients will likely respond to a specific anti-cancer therapy and to monitor their response to therapy. Because of our investments in faculty and infrastructure, Stanford Radiology was selected in 2006 as one of eight institutions in the nation to receive support from the National Institutes of Health (NIH) to develop the CCNE-TR. This Center includes scientists from Stanford and from six other sites across the country: the University of California at Los Angeles; the University of Texas at Austin; the Fred Hutchinson Cancer Research Center; Cedars Sinai; Intel; and the General Electric Global Research Center. The CCNE-TR has greatly expanded our Department's collaborative efforts, and we now work with an additional 35 faculty in more than 20 departments here at Stanford and across the country.
Awards and Honors: March-April 2007

Scott W. Atlas, MD, professor and chief of neuroradiology and senior fellow at the Hoover Institution, has been accorded a grant from the Presidential Fund for Innovation in International Studies to support his research project, "Health Care for One Billion: Experimenting with Incentives for the Supply of Health Care in Rural China." Along with Scott Rozelle, PhD, Helen F. Farnsworth senior fellow at the Freeman Spogli Institute for International Studies, Dr. Atlas is examining the effects of existing health policies and institutions in rural China. Their project also studies a practice common in China's healthcare system that allows physicians both to prescribe drugs and to receive a large profit from drug sales. Their research experiments with realigning the incentives surrounding this practice. Dr. Atlas has also recently received a Fulbright Scholar Award to collaborate with leaders in China on improving and restructuring the healthcare system in China, a system that has dramatically devolved over the course of the past decade despite significant economic development in other areas. This year, Presidential Fund grants at Stanford were awarded to faculty teams composed of faculty from different disciplines who do not usually work together. Their projects had to involve collaborative research and teaching and to address one of three primary areas: the societal and security implications caused by China's female deficit; incentives to provide healthcare services in rural China; and the impact of higher education's rapid expansion in developing countries. For more information, please see http://news-service.stanford.edu/news/2007/february28/presfund-022807.html.

2nd row: Nancy, Ofelia, Lorna
3rd row: Louie, Jose, Kiki (LaKitra), Kim
4th row: Greg, Peter
The digital image specialists at the SHC Digital Image Library have a cumulative work experience of over 164 years. The specialists on staff and their years of service to our Department are as follows: Carla (over 33 years); Deborah, Digital Image Library Supervisor, (over 25 years); Greg (over 20 years); Jack (over 16 years); Jose (over 16 years); Peter (over 13 years); Ofelia (over 11 years); Lorna (over 6 years); Louie (over 6 years); Orwson (over 5 years); LaKitra "Kiki" (over 5 years); Nancy (over 5 years); and Kimberly "Kim" (over 3 years).
Our team provides a myriad of services for our Department as well as all other Hospital and clinical departments. These duties include processing requisition forms and sending patient tracking forms to the reading area for radiologists to dictate. Daily reports are utilized by the digital image library staff to insure all imaging exams have been dictated in a timely manner to meet departmental standards. The staff also import outside images from films or CDs into the Picture Archiving and Communications System (PACS) for comparison purposes. Patient radiology exams are prepared in the format of a CD for case managers and facilities external to Stanford when a patient has been discharged. The staff pulls and delivers exam studies for patient appointments at 10 different clinics. The number of clinic "pulls" has decreased from 20 clinics down to 10 clinics since the introduction of the PACS system.
In addition, the digital image specialists answer phones and manually compile exam folders on the PACS system for the musculoskeletal (MSK) section as well as the chest section. The transcription quality assurance (QA) duties are performed on a daily basis through the combined efforts of the outside transcription company, the radiologist, and the digital image library staff. At least four of the imaging studies that the staff processes on a daily basis are for law suits. They are divided into two categories: litigation cases, which implicate the Hospital as a defendant who is being sued by a patient, and subpoenas, which are used for evidence in a lawsuit and do not directly involve the Hospital as a defendant.
Most of the exam requests processed by the Digital Image Library staff are in digital format, but plain film copies are made upon request.
Life before Match Day: An Interview with Melissa Enriquez, MD, MPH, Former Stanford Medical Student
When she was five years old, Melissa Enriquez decided that if she could not be a cat, she wanted to be a physician. After attending Harvard University for her undergraduate education, she spent six years at Stanford University: four years as a medical student; one year researching issues related to women's health and infectious diseases; and one year completing the Master in Public Health (MPH) Program at the University of California, Berkeley. She has spent the past year applying to internship and radiology residency programs. For her internship, she applied to transitional programs, which offer a rotational mix of surgery, medicine, and emergency room (ER) medicine. Because her fiance, Leroy Sims, MD, was a Stanford medical student as well, Dr. Enriquez coupled matched so that she and her fiance could be geographically connected. She completed seven internship interviews.
During her residency interviews for radiology programs, she spoke to as few as three people and as many as six. Each interview was typically 15 to 25 minutes long. Her longest interview was 30 to 40 minutes long. Dr. Enriquez approached the residency interview process as an opportunity to meet somebody new and to share her story with someone else: "Who else is going to let you talk about yourself for 20 minutes? No one else is going to let you do that so it's great! Who else comes up to you and says 'tell me about your family'?"
Why did you decide to become a physician?
"In medicine, as difficult as this road is, you always know at the end of the day that you are making a contribution for the good. It doesn't have to be 'I saved someone's life,' or 'I invented some cure,' or something. It really just has to be that everyday you know that you are engaged in something that has some higher meaning."
How did you decide to become a radiologist?
"I went to my advisor, and he suggested coming up with six professional goals and six personal goals and scoring all the specialties across those goals, which I did, but I thought to myself, 'I want to go with gut feeling.' His point of view was that gut feeling can't be everything. You need to back it up with looking at your long-term plan and not just how you feel right now. If I went with gut feeling, I probably would have picked something I liked right now, and I may have been unhappy with it 15 years down the road. While I was doing this spreadsheet, I was also taking the diagnostic radiology elective, which is taught by Dr. Mindelzun. I liked it. I was reading the book for fun. It was suggested reading, but I don't think the rest of the class was necessarily doing all the reading, and I almost read the whole book just sitting in coffee shops. I thought,'I like this stuff,' and I went to my advisor halfway through the clerkship. He arranged for me to go to the interventional radiology (IR) suite the last two weeks every morning, which gave me the opportunity to participate a little more as a medical student and kind of address my concerns about radiology not having enough patient contact. After just those two weeks of meeting more people in the Department, I was really starting to think 'I can think of myself doing this. I like technology, having been a web developer in the past, and I like the people in the Department.' They were really laid back and supportive. I thought, 'Other people can't picture themselves sitting in a reading room for hours,' but I had no problem with doing that, having written code for hours on end and forgetting to eat and go to the bathroom."
Have you chosen a specialty?
"Picking a medical school was a lot easier than picking a specialty. A lot of people stress themselves out over where to go, etc. I think that at that age, knowing that you're going to go somewhere for four, five, or six years is an adventure. It's exciting and no matter where you go, you're going to get a great education. Picking a specialty is your life; it determines what your day-to-day life will be like forever, or for as long as you're working at least, so I think it is a lot harder."
"I am interested in academic medicine. I like teaching. I taught as a teaching assistant for nine quarters: all during medical school. During the preclinical years, it was fun. I think that's what keeps you young: hanging out with younger people [medical students] whom you teach a year after you took the course. I just made sure that I got to know the material a little bit better, and I liked the challenge. These are extremely intelligent, resourceful people. Trying to add value to their educational experience is challenging, and I think that's always going to be the case if you are in academic medicine, and you are learning how to teach adults while keeping up with new technology and new developments. You are always going to be stimulated, and I really like that."
What were your residency interviews like?
"I knew I wanted to do radiology--that process was easy. Then you have to choose which programs to send your applications to and for that I turned to faculty, like Dr. Jeffrey, and I asked for advice from Dr. Mindelzun. He met with us, took us to pizza, and talked about programs. He mainly gave us advice about the interview process: about being you, being natural, and having a conversation. The funniest thing he said to us was not to be like the KGB. He had an anecdote about an interviewee who came and just wouldn't give up information--one word answers. I will always remember that because it's hilarious; I can't imagine someone going into an interview and being completely closed."
What were your interview questions like?
"I've had some topics that focus on my family life or my history of immigration to the U.S. I've had other ones that focus on my MPH and what I want to do with it; others that talk about research; and others that talk about when I was a travel guide writer for a summer. I think that in radiology, the interview process is very conversational. There are no scary questions. Even the people who may be a little bit confrontational are never that confrontational."
What was the hardest interview question you were asked?
"'What was the hardest decision that you ever had to make?' Why is this so difficult a question when we've all had many difficult decisions to make? I think that most of us, once we've made the difficult decision, embrace it and don't look back on it like it was tough or something to regret. It was really hard for me to answer. So, I thought 'Have I really been making easy decisions all my life?' They never seem that difficult in retrospect in looking back over my life."
Do you have any advice for other medical students regarding the residency application process?
"Be aware of geographical biases for interviews. I was told that if I wanted to apply to New York and get an interview, I would have to have family in New York or do a rotation away in New York. No one believes that you will ever leave California. They have stories about people from California who sign up for interviews and then don't show up. The reputation is that you wouldn't leave--that everything is so beautiful and golden in California that you wouldn't dream about leaving. That was something I never would have anticipated."
"They want happy, constructive, and productive residents. The tough thing is that if you don't know about geographical bias as an applicant you might think you can just get an interview, and you might not do the things you need to do, such as go there for a rotation or write statements that are specific for that area."
"Why are the women applicants one [woman] to three [men]? Pediatrics and obstetrics/gynecology tend to have more women. On the interview trail, there were days when it was just me or 1 other woman and 10 men. Dr. Desser mentioned a study that claimed that women thought that radiology involved a lot of radiation, and therefore, didn't want to do it. It makes sense. Every time I tell a friend or family member, they think I will be taking X-rays. They don't say CT. They think just the name of the field implies radiation. I don't know why it [radiology] would be woman unfriendly. We are planning on doing a session on women in radiology and discussing this. I have another theory that it's based on the number of women in the physical sciences. It might be that. In radiology, you have to take physics, but that shouldn't preclude any of us. There are not that many doctors or medical students who like physics. I also wonder if they see the specialty as technology heavy. If people think it's only about radiation, there must be a lot of other misconceptions about radiology."
Match Day, March 15, 2007
When Melissa Enriquez was handed her envelope at the School of Medicine's annual Match Day ceremony on March 15, 2007, she thought, "Oh my god, my future is in this envelope!" (https://med-intranet.stanford.edu/education/spotlight/). She and her fiance, Leroy Sims, MD, were pleasantly surprised when they opened their match envelopes. Both of them will be headed to the University of California, Los Angeles (UCLA), which was their top choice as a couples match. Dr. Enriquez will be doing her transitional-year internship at Harbor-UCLA and residency at UCLA, while Dr. Sims will be completing his internship and residency in emergency medicine at Harbor-UCLA. Drs. Enriquez and Sims were 2 of 68 Stanford medical students who participated in the Match Day residency assignment process, along with 17,000 medical students across the United States. Stanford medical students matched 100%, and more than 85% matched with one of their top three choices. For more information on Match Day, please see "Hugs and High-Fives as Medical Students Meet Their 'Match'" by Tracie White (https://med-intranet.stanford.edu/education/spotlight/) and the Dean's Newsletter (March 26, 2007) (http://deansnewsletter.stanford.edu/).
Match Day, March 15, 2007
The 2007 National Resident Matching Program results were announced on Thursday, March 15, 2007, and it was another banner year for Stanford Radiology. After a very successful recruiting season, we are welcoming nine new Stanford Radiology residents for 2008. Here are some brief descriptions of our new residents.
Stacey Crawford, MD, MBA, Dartmouth Medical School
Stacey Crawford is the daughter of a radiologist and will be the first woman to graduate from Dartmouth with a joint MD/MBA degree. While at Dartmouth, she conceived and developed their mini-MBA program for medical students. She also worked on a tele-ultrasound project and tested it in Central America.
Albert Hsiao, MD, PhD, University of California, San Diego, School of Medicine
Albert Hsiao studied biology and computer science at Caltech before entering the Medical Scientist Training Program at the University of California, San Diego. His PhD in bioengineering and his work in bioinformatics earned him several prizes, including a Radiological Society of North America (RSNA) trainee research prize. This year, as a visiting student on our cardiovascular imaging (CVI) rotation, he took to the computer graphics TeraRecon workstation like a fish to water. In his interview with me, he confessed that even as a child he would reprogram his video games to make them run faster. Albert hopes to contribute both to our image processing group in the 3D lab and the bioinformatics efforts of Dr. Gambhir's Molecular Imaging Program at Stanford (MIPS).
Michael Kim, MD, Joan & Sanford I. Weill Medical College of Cornell University
Michael Kim is originally from New Jersey and studied genetics and microbiology at Rutgers before entering Cornell Medical College. He is the founder of the Cornell Radiology interest group. Michael worked on the neuroradiology service with Dr. Atlas as a visiting medical student, and we are delighted he decided to come and join us for residency.
Deborah Lee, MD, David Geffen School of Medicine at the University of California, Los Angeles
Deborah Lee grew up in southern California and graduated as salutatorian of her undergraduate class at the University of Southern California, achieving the highest GPA of any woman student. At UCLA medical school, she did research on pancreatic cancer and traumatic brain injury, as well as work on protein folding. She is a big Martin Scorcese fan and is delighted to be moving to the Bay Area and closer to her sister who works at Guidant.
Jared Narvid, MD, University of California, San Francisco, School of Medicine
Jared Narvid was a Russian and Eastern European studies major at Yale before embarking on a neuroimaging fellowship in Washington DC in the year before medical school. As a medical student at the University of California, San Francisco, he has conducted neuroanatomic studies of face recognition in patients with neurodegenerative diseases.
Srihari Sampath, MD, PhD, Joan & Sanford I. Weill Medical College of Cornell University (on left) and Srinath Sampath, MD, PhD, Joan & Sanford I. Weill Medical College of Cornell University (on right)
Srinath and Srihari Sampath are twin brothers originally from southern California. Both have already attracted notice at the national level for their brilliant work in different fields of molecular genetics. At Stanford, they hope to contribute to the Molecular Imaging Program--as well as to our intramural basketball team.
Anobel Tamrazi, MD, PhD, University of Illinois College of Medicine at Urbana-Champaign
Anobel Tamrazi and his family were Christian refugees who fled Iran and eventually settled in the Bay Area. After attending San Jose State University, Anobel entered the Medical Scientist Training Program at the University of Illinois at Urbana-Champaign where he researched the fluorescent labeling of estrogen receptors. During medical school, he worked in Dr. Gambhir's lab as a visiting student, and he hopes to continue that work during residency.
Amy White, MD, Georgetown University School of Medicine
Amy White is a former competitive cyclist and Olympic hopeful who now applies her considerable energies to the radiology realm. As a medical student at Georgetown, she worked on several manuscripts and grants in interventional radiology and was a winner of the RSNA student research award.
Life after Match Day: An Interview with Pejman Ghanouni, MD, PhD, First-Year Stanford Radiology Resident

While in the MD/PhD program at Stanford University, Peji Ghanouni left Stanford to join several collaborative scientific efforts in Copenhagen, Baltimore, and Portland, and he spent two years at a start-up biotech company. Returning to Stanford to finish his last two years of medical school after completing his PhD and working in the biotechnology industry gave him an appreciation of the different opportunities within medicine; this perspective ultimately developed into an interest in the new advances within the field of radiology.
Dr. Ghanouni was accepted into the Radiology Residency Program at Stanford. He was particularly excited about the opportunity to apply his graduate research skills earned studying adrenergic receptors to molecular imaging. While earning his PhD in molecular and cellular physiology, Dr. Ghanouni studied how adrenergic receptors respond to hormone binding. To investigate how a hormone causes a biophysical change and what that conformational change means for protein activity, Dr. Ghanouni fluorescently labeled purified receptors, using similar approaches to molecular imaging methodologies. He hopes to apply what he has learned to this field.
Why did you choose radiology?
"I stumbled upon radiology. As a medical student, I took an introductory radiology course taught by several of the faculty here, including Dr. Mindelzun, and I really enjoyed it. Through a rotation with Dr. Mindelzun that followed the class, I saw that as a radiologist, one has to know something about everything. Actually, a lot about everything. For each disease, a radiologist has to blend knowledge of clinical symptoms, pathology, treatment, prognosis, and, of course, what the disease looks like using various imaging modalities, all to arrive at a reasonable list of possible diagnoses."
"The breadth of the field appealed to me. Another thing I liked about radiology was that it's a field that tends both to reinvent and to expand itself. Some procedures originally done by radiologists are now performed by other specialists. Our field has moved on to invent new things, whether evolutionary new algorithms for imaging, or, as in molecular imaging, potentially revolutionary new technologies and applications. I found those possibilities appealing as well. Even during the course of my training, the field will develop new imaging approaches. I'm fortunate to be at one of the places where those technologies are being developed and tested."
"I saw how fundamental radiology is to clinical decision making. Now as a resident, I enjoy my involvement in evaluating a patient, merging what we provide by looking at images of a patient's pathology with the clinical information that physicians provide. We're a service to the rest of the hospital. I appreciate that aspect of it. I like interacting with my colleagues. I've been here long enough to I recognize a lot of faces when they come and talk to us about whatever is going on with their patient, and I enjoy working with them to figure out what might be wrong."
"The last thing that was missing for me was that, as a PhD, I wanted to pursue academic research. I wasn't sure how, with my molecular biology and biochemistry background, I would be able to pursue research and radiology. The people I knew who have done research in radiology have had a physics or engineering background. They performed fundamental research on engineering, computer science, and algorithm development. It wasn't until Dr. Gambhir came that I saw an opportunity to apply my own background to research in the molecular imaging program here. I think that opportunity clinched my decision to pursue a career in radiology."
What was the residency interview process like?
"Interviewing is tiring. You have to travel, and deal with jet lag, and hotels, and driving directions, make a showing at the pre-interview dinner, try to answer the interviewers' questions intelligently, and then do it all again the next day or week."
"By the time an applicant gains an interview, everyone's academic record is similar. At that point, it has more to do with how you present yourself personally. How do you communicate? Are you easy to get along with? Are the interviewers, your future colleagues, likely to want to spend the next four years in a dark room with you?"
"Usually, there are five half-hour interviews. As an applicant, I was trying to get a sense of the personality of the various programs. And of course, the interviewers were trying to get a sense of me. Later, the interviewers get together and discuss their impressions of the applicants. It's not scientific, but it seems to work. Each program tries to attract people with particular personalities, reflecting the personalities of the people who are already there."
Where did you do your internship?
"I did a transitional internship at Santa Clara Valley Medical Center, which is the local county hospital. As a transitional intern, I rotated through the specialties--surgery, obstetrics/gynecology, pediatrics, medicine, emergency medicine--for one or a few months each, as opposed to spending a full year as a surgery or medicine intern. Through this type of internship, I was re-exposed to the various fields of medicine, but now as an intern, I had more responsibility in managing my patients. I loved it. The Valley is a fun place. Like most county hospitals I've heard of, the interns play a very hands-on role in managing the patients. Plus, the pathology that we saw there was amazing. All too frequently, our patients presented late in the course of a disease, and we would see and learn to manage the consequences of that."
"During some of my internal medicine months, I also rotated through Stanford. Since I'd been here as a student, I was generally familiar with the organization here. Stanford tends to be much more specialized, with fellows in every subspecialty helping to manage the patients. On the other hand, there are complex patients that I helped care for here that aren't going to be seen at most hospitals."
What has your first year as a resident been like?
"In a word, humbling. After all of these years of study, I almost feel that all I learned was the equivalent of the alphabet, and now I actually have to learn to read and write. It can be a frustrating transition; as an intern, I could do a good job taking care of very sick people. Now as a first-year radiology resident, I don't know enough to do more than listen and read. Basically, I've spent the year trying to build a foundation of knowledge, in preparation for taking call. We are eased into call, with lots of supervision by more senior residents, fellows, and attendings. On the other hand, by the time you are a third-year radiology resident, you are ready to manage most situations yourself. So when somebody comes to the Emergency Department (ED) and you're looking at their films, trying to figure out what's wrong with them--a surgeon may walk in to talk about another patient, a pediatrician may walk in, an internist, all trying to figure out what's wrong with their patients--you have to know the pathology for all of those patients. It's exciting that I'll be able to do that soon, but it's daunting because I have a lot to learn before then. Our class is about to start call, and while there is an element of anxiety, from what everyone tells me, you tend to learn a lot on call, in part because of the level of responsibility. I'm looking forward to it."

Is Iodine Safer than Gadolinium in the Renal Impaired Patient?

By Bob Herfkens, MD
Why nephrogenic systemic fibrosis (NSF) occurs in some patients who receive gadolinium-based contrast agents for MR imaging is still a mystery. First recognized in 1997, NSF is a rare disease occurring in renal insufficiency that causes a thickening of the skin as well as the muscles and vital organs. In the summer of 2006, NSF was linked to the administration of a high dose of gadolinium in patients with renal failure. Recently, the FDA announced an advisory, cautioning the use of gadolinium chelates in patients with moderate renal failure (gfr<60) and recommending discontinuing the use of it in patients with severe renal failure (gfr<15), unless prompt dialysis is arranged.
So, is gadolinium safe to use for our MR imaging studies? Our current MRI screening form contains a question about the presence of kidney (renal) disease. If this is checked "yes," indicating that the patient does have a history of kidney disease, the technologist must notify the radiologist before the MRI scan is initiated. The radiologist must determine if the MRI scan should be performed and if performed, if the scan should be with or without contrast agents.
In all patients with any history of renal disease, the use of gadolinium compounds should be minimized. Specifically, the use of Omniscan must be avoided. Patients with normal renal function and/or patients with no known history of renal failure who are receiving gadolinium contrast agents should voluntarily hydrate themselves after their studies.
Clearly, a whole generation of radiologists has grown up relying on the use of gadolinium. However, it is widely overlooked that most diagnoses can be made with non-contrast exams. We are too reliant on contrast enhanced exams. Time to dust off those old protocols! Because NSF has only been associated with renal failure patients, the wholesale use of iodinated contrast enhanced CT in this group should be weighed against the risk of iodinated contrast induced nephropathy. More news on this topic is forthcoming.

THE CODING CORNER: Where All of Your Coding Questions Are Answered

By Darryl Costales

ULTRASOUND OF THE ABDOMEN
Question: What anatomical structures need to be imaged and mentioned in a dictated report when performing an ultrasound (US) of the abdomen complete, CPT 76700 (.81 WRVU's)?
Answer: According to the 2007 CPT-4 coding manual, a complete US of the abdomen includes the liver, spleen, gall bladder, common bile duct, pancreas, kidneys, the upper abdominal aorta, and inferior vena cava, including any demonstrated abdominal abnormality. All of these structures need to be imaged and dictated in the report in order to bill correctly.
If you image and dictate a single organ, quadrant, or follow-up exam, then the appropriate charge would be an ultrasound abdomen limited, CPT 76705 (.59 WRVU's).
Have you got a question for the Coding Corner on billing, procedure codes, modifiers, or other related issues? Is there a topic you would like to see in a future issue? Just looking for general information? Ask us and we will do our best to answer your questions clearly and accurately (darrylc@stanford.edu).
HIFU Symposium a Great Success

(Image courtesy of Mark Riesenberger)
On Monday, February 5, Stanford hosted a Symposium on MR-guided High Intensity Focused Ultrasound (MR-guided HIFU). The symposium was developed to introduce the new technology to our faculty and students and to demonstrate both the clinical capabilities and research opportunities for focused ultrasound techniques. The interdisciplinary nature of this exciting new treatment modality proved to be a great draw throughout the Stanford School of Medicine (SOM).
Recently installed on the 3T MRI in the Lucas Center, MR-guided HIFU was developed by InSightec and is a promising technique for the next generation of non-invasive therapy systems. With this technology, ultrasound energy is focused at a point deep within the body. One very exciting use is the thermal ablation of targeted tissue. This can be done with minimal heat deposition at the skin surface and without skin puncture or incision. MRI temperature imaging provides real-time control of the treatment.
The symposium featured leading world experts who described their experiences, current projects, and vision for the future. The talks covered HIFU applications for uterine fibroids, the prostate, the neurological system, the liver, the spleen, general abdominal tumors, and the bone. A hands-on session focusing on uterine fibroids (currently the only FDA approved technique) followed the symposium. This technology offers great potential for replacing invasive procedures and providing therapeutic alternatives to millions of patients.
We were delighted to welcome over 100 faculty, students, and residents from throughout the SOM to our event. The audience included representation from the Departments of Urology, Obstetrics & Gynecology, Comparative Medicine, Radiation Oncology, Otolaryngology, Pathology, Orthopedics, Surgery, and, of course, Radiology. From outside the University we had attendees from Hewlett Packard (HP); General Electric (GE); the Lahey Clinic; the University of California, San Francisco; the University of Wisconsin, Madison; and the Focused Ultrasound Surgery Foundation.
Within our own faculty, Kim Butts Pauly, PhD, Graham Sommer, MD, Rusty Hofmann, MD, Bob Herfkens, MD, and Bruce Daniel, MD, have begun to develop research programs utilizing HIFU.

Continuing Medical Education
Stanford's Continuing Medical Education (CME) Program has grown into the leading radiology CME effort in the country. In FY 2006, we welcomed over 3,300 registrants to 14 courses from more than 24 countries. Our symposia are developed to educate radiologists, technologists, and scientists about impending transitions to new and emerging technologies. In 2006, we grew our program by introducing courses on PET/CT and molecular imaging, small animal imaging, and the treatment of venous disease. Our International Symposium on Multidetector Row CT (MDCT), now in its eighth year, is one of our most successful programs. We had a record-breaking year in 2006 with 950 attendees. The meeting has been groundbreaking as a new model for education in radiology, and its influence on the field is unmatched.
