Diagnostic Radiology

I am a diagnostic radiologist with special expertise in gastrointestinal cancers. I use leading-edge methods to diagnose and stage esophageal cancer, stomach cancer, small intestine cancer, and colon cancer. These methods include MRI, PET, CT, virtual colonoscopy, CT enteroclysis, CT enterography, and barium studies. I have been practicing radiology for more than 25 years and have been at MSK since 1994.

As Director of the CT Section and Director of Gastrointestinal Radiology, I work closely with surgeons, medical oncologists, pathologists, and radiation oncologists. This allows me to better understand the issues that people with cancer face. As a member of the Colorectal and Esophageal Disease Management Teams, I use my expertise in imaging to prepare and review imaging and clinical data with members of other departments. We work together to provide the best cancer care to our patients.

The level of care at MSK is unparalleled. I enjoy working with oncologists who publish the most-important clinical trials in the most-reputable journals. I enjoy working with my radiology colleagues as we complement one another in our knowledge base. I enjoy working with surgeons due to our shared way of seeing the body. Last but not least, I enjoy working with patients directly. I am a very effective communicator and can learn a lot from them. This helps me interpret their studies.

I am an investigator on three national clinical trials on rectal cancer. My research focuses on improving imaging techniques so that we can predict the response to a treatment earlier on. This will help avoid unnecessary treatment that may be toxic. I am particularly interested in developing better ways to predict a complete response to treatment for rectal and esophageal cancer. This may result in minimal or no surgery. It could help us avoid a situation in which a person has surgery only to later find out there was no remaining cancer in the organ that was removed.

I remain highly involved in medical education. This includes lecturing to residents and fellows, speaking at national and international conferences, and working with the American College of Radiology to develop web-based knowledge programs for the certification of Centers of Excellence in rectal cancer radiology.
