Vascular and Interventional Radiology

Description of division:
Interventional Radiology is minimally invasive, image-guided treatment of different medical conditions through innovative techniques that once required open surgery. Using different imaging technologies like CT, ultrasound and x-ray guidance, interventional radiologists can treat a variety of conditions from vascular disease, cancer and beyond.

The Interventional Radiology Division at Western University is comprised of 10 faculty members committed to advancing the subspecialty of IR with compassionate and high-level patient care, along with contributing to the science of IR with teaching and research. The division involves the delivery of IR care at three sites, including the Victoria and University campuses of LHSC and St. Joseph's Health Care London. This includes treatment of adult and pediatric patients with a variety of IR procedures supporting multiple specialties. IR at Western is also a clinical service, with an outpatient consultation service and admitting for some patients in hospital following IR procedures.

Many of our faculty lead the country in various administrative roles, including the Canadian Association for Interventional Radiology (CAIR) and the Canadian Association of Radiologists (CAR), including roles at the Royal College of Physicians and Surgeons as examiners and curriculum development. They are leaders provincially, with roles within the interventional oncology working group at Ontario Health and CorHealth Ontario. In addition, our faculty are often speaking at national and international conferences in IR and involved as journal reviewers for the specialty.
