Body Imaging
Description of division:
The Division of Body Imaging consists of 30 Faculty members, located at three different hospital sites, including University Hospital, Victoria Hospital, and St. Joseph’s Health Care. Our Faculty have specialized fellowship training in the interpretation and management of diseases of the abdomen and pelvis, as well as obstetrical and thyroid imaging. Division members are experts in the interpretation of computed tomography, magnetic resonance imaging, ultrasound, molecular imaging, x-ray, and fluoroscopy.
Our Division is committed to providing excellence in clinical care, as evidenced by our Faculty who are members of regional, national and international advisory boards, including Cancer Care Ontario, Canadian Association of Radiologists (CAR), Radiology Society of North America (RSNA) and Society of Abdominal Radiology (SAR). Several faculty members are also cross-appointed at the Lawson Research Health Institute and the Department of Oncology.
Academic and clinical interests of our Division members are wide-ranging, and include gastrointestinal imaging (including CT and MR Enterography, CT Colonography), hepatobiliary imaging (including transplant assessment and hepatocellular carcinoma), oncologic and genitourinary imaging (including fusion imaging and targeted biopsy of the prostate).
