Welcome to the Department of Radiology

Richmond University Medical Center (RUMC) Diagnostic Radiology Residency is a fully accredited ACGME four-year resident training program.

RUMC, formerly St. Vincent’s Medical Center Staten Island, is a large community hospital that serves as a Level I Trauma Center and a major Stroke Center for Staten Island. The radiology group is composed of Board-Certified, fellowship-trained attending radiologists in all subspecialties. There are two radiology residents per year, for a total of eight current residents. The attendings and residents perform a full range of diagnostic and therapeutic imaging procedures at two locations, which include the main hospital campus and the adjacent primary outpatient imaging center, Regional Radiology. The radiology department at the hospital performs and interprets a full gamut of imaging modalities. We provide state-of-the-art outpatient imaging modalities such as PET/CT fusion, cardiac CT, virtual colonoscopy on a new 64-detector CT, digital mammography and whole body MRI including breast MRI and MRA.

The residency training itself mainly occurs at the Richmond University Medical Center Main Campus. Residents cover the core rotations, which include the ER rotation, gastrointestinal and uroradiological fluoroscopy, pediatrics, cardiovascular and interventional radiology, neuroradiology, and body imaging rotations. The other rotations include nuclear medicine, musculoskeletal/bone radiology, mammography and women’s imaging, ultrasound, thoracic, and Body MRI. There is a night float system during the week and 24-hour call on weekends. “Buddy call” is done by the first year residents until their second year. Attending backup, senior resident backup and nighthawk teleradiology is always provided. Residents are given 4 weeks of vacation per year as well as stipends to numerous conferences, including a fully paid AIRP (formerly AFIP) Conference as well as board review courses. Lectures are given by our own staff and supplemented by outside lecturers whom we hand pick to supplement our radiology education and board review.

The residency is a small but intimate group of people. We get along and enjoy each other’s company both in and out of the hospital; this leads to a warm, congenial working atmosphere. Moreover, the residents and attendings have a great relationship. Having Manhattan and Brooklyn only minutes away also helps. In fact, our residents and attendings commute from all over the metro area to the hospital each morning – current and former residents have resided in Manhattan, Brooklyn, Staten Island, Queens, Long Island and New Jersey.
