I am a diagnostic radiologist with special expertise in gastrointestinal malignancies, and I use cutting-edge methods (MRI, virtual colonoscopy, PET and CT scanning, CT enteroclysis, CT enterography, and barium studies) to diagnose and stage cancers of the esophagus, stomach, small intestine, and colon. I also serve as director of the Radiology Department’s CT section and director of gastrointestinal radiology. I serve as Director of CT and Director of Gastrointestinal Radiology at Memorial Sloan Kettering.
As a member of the colorectal cancer Disease Management Team I collaborate closely with Memorial Sloan Kettering’s colorectal surgeons and gastroenterologists to accurately diagnose and stage colon cancer, malignant bowel obstruction, recurrent rectal cancer, and other gastrointestinal problems. I very much enjoy working with patients, and learn as much as I can from them about their symptoms to aid my interpretation of their images. I also enjoy explaining the imaging findings to patients to give them a better understanding of their illness.
My research interests include early detection of colon cancer through combined structural and molecular imaging approaches. For this work I have been awarded three grants (from The Society of Memorial Sloan Kettering Cancer Center and The Society of Gastrointestinal Radiologists). I am particularly involved in research using MRI to improve rectal cancer staging. As director of CT, I am interested in how best to use Dual Energy CT, and in keeping radiation doses as low as possible while obtaining maximum information.
I lecture and present research at national and international meetings of professional groups such as the Society of Gastrointestinal Radiologists and the Radiological Society of North America. I am also a member of Memorial Sloan Kettering’s Research Council and have input on the radiologic aspects of every research study performed at the Center. As a reviewer for several leading journals I have rapid access to the most recent advances in radiology and oncology.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.Learn more
