Radiology

Host Dr. Jason Birnholz talks with experts on the conference floor from the Radiological Society of North America's 96th Scientific Assembly and Annual Meeting in Chicago. His guests include:

• Dr. Candice Aitken, radiation oncologist and assistant professor of medicine at Dartmouth Medical School
• Dr. Jacques Souquet, founder and CEO of SuperSonic Imagine
• Dr. Judy Kalinyak, chief medical officer of Naviscan
• Dr. William Denman, chief medical officer of GE Healthcare

It is apparent to most physicians that patients at high risk for having a cardiovascular event should be screened, but what about those patients who fall into the intermediate risk category (classified using the Framingham risk score)? Dr. Prediman Shah, director of the division of cardiology at Cedars-Sinai Heart Institute in Los Angeles, suggests that screening asymptomatic, intermediate-risk patients for subclinical atherosclerosis using non-invasive imaging might be beneficial. Dr. Shah also discusses the limitations of relying solely on the Framingham risk score, and recommends additional ways to classify a patient's risk for developing a cardiovascular event. What specific screening tests are best for detecting subclinical atherosclerosis? Dr. Janet Wright hosts.

Obscure gastrointesinal bleeding can pose investigational challenges. What are the potential causes of obscure GI bleeding? After initial negative upper endoscopy and colonoscopy tests are performed, what new technologies can help physicians more effectively detect small bowel abnormalities? Dr. Jonathan Leighton, professor of medicine and chair of the division of gastroenterology at the Mayo Clinic in Arizona, and Dr. Moshe Rubin, director of gastroenterology and program director of the GI fellowship training program at New York Hospital Queens Medical Center and the Weill-Cornell Medical College in New York, discuss the roles of small bowel capsule endoscopy, balloon-assisted enteroscopy, spiral enteroscopy, and CT enterography in evaluating patients with obscure GI bleeding. Dr. Jay Goldstein hosts.

Tune in to hear important highlights from research findings presented at the Radiological Society of North America's 2009 Scientific Assembly and Annual Meeting, November 29th through December 4th.

These interviews were recorded at the Radiological Society of North America's 95th Scientific Assembly and Annual Meeting, which took place November 29th through December 4th, 2009, in Chicago.

Host Dr. Jason Birnholz talks with Dr. Stamatia Destounis, associate clinical professor of radiology at the University of Rochester, and a practicing radiologist at the Elizabeth Wende Breast Care Center in Rochester, New York. Dr. Destounis presented a paper entitled "The Role of Ultrasound Elastography for Differentiating Benign from Malignant Breast Lesions: Can Benign Result Biopsies Be Reduced?"

These interviews were recorded at the Radiological Society of North America's 95th Scientific Assembly and Annual Meeting, which took place November 29th through December 4th in Chicago.

Host Dr. Jason Birnholz talks with Dr. Rozemarijn Vliegenthart, from the University Medical Center Groningen in the Netherlands, who presented at the conference a paper entitled, "High Prevalence of Treatable Severe Coronary Artery Disease: Findings in a Randomized Controlled Trial in Cardiac Asymptomatic Peripheral Arterial Disease Patients." Dr. Birnholz also sits down with Dr. Asim F. Choudhri, from Johns Hopkins University in Baltimore, to talk about tele-radiology and smartphones.

This program features Dr. David Cosgrove, professor of clinical ultrasound, Imperial College School of Medicine, and honorary consultant in radiology at the Hammersmith Hospital in London. He is an expert in ultrasound, known around the world, and is the author of numerous publications. He speaks with host Dr. Jason Birnholz about a new form of ultrasound imaging— elastography, or sheer wave imaging — for detecting breast cancer.

Next, Dr. Birhnolz sits down with Dr. Michelle Brown, associate professor of radiology at the University of California, San Diego. She is presenting research on detection of placenta accreta using MRI. The incidence of placenta accreta has increased ten-fold since 1950, as the incidence of the primary risk factor, cesarian section, has also increased.

These interviews were recorded at the Radiological Society of North America's 95th Scientific Assembly and Annual Meeting, which took place November 29th through December 4th in Chicago.

Host Dr. Jason Birnholz reports from the Radiological Society of North America's 95th Scientific Assembly and Annual Meeting, which took place November 29th through December 6th in Chicago. In this segment, he speaks with Dr. Wendie Berg, from Johns Hopkins University, about early detection and breast cancer, and Dr. Alexis Kelekis, assistant professor of radiology at the University of Athens, about percutaneous disc decompression treatment for herniated disc.

What are the limitations of conventional treatment for primary bone cancer and spinal metastasis? How can proton therapy be particularly beneficial for treating primary bone tumors, which are found more often in pediatric patients? And what role can proton therapy play for patients with spinal metastasis? Dr. Michelle Alonso-Basanta, the Helene Blum Assistant Professor in the department of radiation oncology at Penn Medicine, discusses some of the advantages of proton therapy, including precise targeting and reduced toxicity. Dr. Lee Freedman hosts.
