Dr. Ren received his medical training from the Tongji University School of Medicine in Shanghai, China, and a PhD in advanced radiological sciences from the University of Texas Southwestern Medical Center at Dallas. Working primarily with Professor Zhen Cheng in the Cancer Molecular Imaging Chemistry Lab, he brings his expertise in small animal imaging using microSPECT and microPET to the In Vivo Cellular and Molecular Imaging Center at Stanford (ICMIC) Program. Dr. Ren's research centers on the development of different molecular probes, including both small molecules and peptides, to target specific tumor biomarkers such as the MC1R receptor; melanin contents in malignant melanoma; and HER2/EGFR in breast cancer. He has already successfully demonstrated the potential of the molecular probes ReCCMSH, Benzamide Analogs, and Affibody molecules in preclinical animal models using microPET. He continues to work on the development of new probes as well as a novel image-guided theragnostic scheme for the management of breast cancer and lung cancer.

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 . . .

State-of-the-art CT scans taken by Dr. Rebecca Fahrig are featured in the exhibit "Very Postmortem: Mummies and Medicine" at the Legion of Honor, one of the Fine Arts Museums in San Francisco. Her scans were used in constructing a three-dimensional "fly through" movie of the anatomy of the 2,500-year-old mummy of the Egyptian Priest Iret-net Hor-irw. Chris Beaulieu, MD, PhD, chief of musculoskeletal imaging in the Department of Radiology, also lent his expertise in determining the anatomy of the mummy's musculoskeletal structure.

According to a recent article in Stanford Medicine News, "Stanford Scans of Mummy to be Featured in San Francisco Museum Exhibition," visitors will
be able to watch "visual navigations through the mummy’s anatomy, zooming in to inspect what remains of his internal organ systems and then swooping back out through the wrappings. It’s even possible to see objects, such as small amulets, buried with the mummy and hidden from view since its burial." ]]> http://radiology.stanford.edu/blog/archives/2009/11/stanford-radiol-7.html http://radiology.stanford.edu/blog/archives/2009/11/stanford-radiol-7.html Fri, 06 Nov 2009 14:00:00 -0800 Dr. William Kuo was recently featured in a Stanford Medicine News article and national press release entitled "Study Reveals Life-Saving Treatment for Pulmonary Embolism." Dr. Kuo discussed the results from his study published in the November 2009 issue of the Journal of Vascular and Interventional Radiology (20(11):1431-1440). Analyzing global data regarding the use of catheter-directed therapy for massive PE, he and his colleagues discovered that the therapy was life-saving in 86.5% of the 594 cases they studied. Dr. Kuo published his findings along with co-authors Lawrence Hofmann, MD, associate professor and chief of cardiovascular-interventional radiology; Daniel Sze, MD, associate professor of radiology; John Louie, MD, assistant professor of radiology; Jarrett Rosenberg, PhD, statistician; and Michael Gould, MD, associate professor of pulmonary and critical care medicine.

“I was hoping my scar would be bigger,” remarked one of our pediatric patients with some disappointment as she undid her bandage. Several days earlier her bone tumor had been successfully treated through a CT-image guided ablation procedure at Lucile Packard Children’s Hospital (LPCH).

To treat children with bone tumors, our Chief of Pediatric Musculoskeletal Imaging at LPCH, Dr. John MacKenzie, has teamed up with Drs. Larry Rinsky, James Gamble, and Meghan Imrie, pediatric orthopedics at LPCH. Because CT-guided RF ablations for osteoid osteoma tumors require a very small incision and leave virtually no scar, other parents have also

Dr. Glazer published his study along with co-author, Sanjiv "Sam" Gambhir, MD, PhD, Virginia & D.K. Ludwig Professor of Radiology & Bioengineering; chief of the Nuclear Medicine Division; and director of the Molecular Imaging Program at Stanford (MIPS), as well as first author Aloma D'Souza, PhD, research scientist and member of the Multimodality Molecular Imaging Lab. Other co-authors include Kim Butts Pauly, PhD, professor of radiology; Samira Guccione, PhD, assistant professor of radiology; and staff scientists Jeffrey Tseng, MD (now at Santa Clara Valley Medical Center in California) and Jarrett Rosenberg, PhD, of the radiology department.

During his twenty years as chair of Stanford Radiology, Dr. Glazer has repeatedly led the Department in generating noteworthy advances in the field. Under his leadership, the Department has established four NIH Centers and has created the Richard M. Lucas Center for Imaging, which serves as a unique international resource. As a second generation radiologist, Dr. Glazer is also devoted to developing patient-centered radiology by optimizing the communication between the radiologist and the patient to improve the quality of healthcare.

Gary M. Glazer, MD, Emma Pfeiffer Merner Professor in the Medical Sciences, will receive the Gold Medal during a special awards ceremony in December at the 2009 Radiological Society of North America (RSNA) Annual Meeting in Chicago.

2009 RSNA Outstanding Researcher
In addition to Dr. Glazer’s award, Sam Gambhir, MD, PhD, has been chosen as the 2009 Outstanding Researcher by the Radiological Society of North America (RSNA) for his unique contributions to the field of radiology. A world-renowned leader in the field, Dr. Gambhir is transforming the imaging sciences and patient treatment through his expertise and leadership in cellular and molecular imaging. He is the second scientist from our Department to be honored with this award in the past 8 years; Dr. Gary Glover won this honor in 2001. This award is given to only one physician and/or scientist each year, and only 15 such awards have ever been given out by the RSNA.

Dr. Gambhir has over 20 years of experience in molecular imaging in both animal models and patients. At Stanford, he serves as chief of the Nuclear Medicine Division; director of the Molecular Imaging Program at Stanford (MIPS); and head of the new Canary Center for Cancer Early Detection. He also leads several large NCI-funded programs, such as the In Vivo Cellular Molecular Imaging Center (ICMIC); the Center for Nanotechnology Excellence Focused on Therapy Response (CCNE-TR); and the Stanford Molecular Imaging Scholars (SMIS) Program. Currently, he is advancing "the merger of in vitro and in vivo diagnostics using novel nanotechnology for earlier disease detection and individualized patient management" (from Inside Stanford Medicine).

Stanford Radiology Residents Bao Do, MD, and Pejman Ghanouni, MD, PhD,
have also been honored with 2009 RSNA Trainee Awards for their outstanding research projects.

Dr. Do (on left) developed his project, "A Natural Language Processor to Detect Uncertainty and Recommendations in Radiology Reports," under the mentorship of Dr. Daniel Rubin, assistant professor of radiology (diagnostic), while Dr. Ghanouni (on right) pursued his research, "Minocycline Prevents Development of Neuropathic Pain by Mitigating Macrophage Recruitment to Site of Nerve Injury as Shown with USPIO-MRI," mentored by Dr. Sandip Biswal, assistant professor of radiology (musculoskeletal).

According to a recent Office of Communication & Public Affairs article, Dr. Wu's award will support his research regarding "ways to keep the body from rejecting human embryonic stem cells. For many years, researchers assumed that these undifferentiated building blocks would be ignored by the body's defense system. Wu's recent research in mice shows that this is not the case. 'It's getting harder and harder to believe that these cells are immunoprivileged,' said Wu. 'Now we need to know what to do about it.'" He will use his award to devise ways to "coax the immune system to tolerate the foreign cells, allowing them to regenerate or heal damaged tissues" (from "Stanford Nabs 13 Top NIH Awards for High-Stakes Research" by Krista Conger, Erin Digitale, Bruce Goldman, David Orenstein, Ruthann Richter, and Tracie White; download PDF at Stanford Nabs 13 Top NIH Awards for High-Stakes Research.pdf).
