Alec J. Megibow, MD, MPH, FACR

Director, Faculty Practice Radiology, New York University Department of Radiology

I completed my medical school training at SUNY Upstate Medical Center in 1974. I immediately began my radiology residency at NYU-Bellevue, and passed the ABR exam in 1978. During that time, I pursued a 1 year fellowship in abdominal imaging. My academic career has been shaped by the introduction of CT scanning into clinical practice. Together with other members of my section we were first to describe the use of CT for diverticulitis and small bowel obstruction. Our work has defined the way in which radiologists and clinicians understand imaging findings in patients with acute pancreatitis. Finally, we were among the earliest investigators in the use of CT for acute appendicitis. I was PI for the pancreas component of an NCI funded RDOG technology assessment trial comparing CT and MRI for patients with pancreatic adenocarcinoma. I have served as President of the Society of Computed Body Tomography and MR, and I am currently President of the Society of Abdominal Radiology. I have served as a founding member of the ACR CT accreditation committee. I was the physician representative for NYU during the formation of the ACR CT Dose Index Registry. My current interests include clinical evaluation of methods for reducing radiation in CT scanning, with special interest in exploring how Dual Energy CT can further facilitate reducing patient exposure.
