What We Do

The Non-Invasive Diagnostic Vascular Lab provides non-invasive diagnostic ultrasound tests on arteries and veins, which our doctors use to confirm a diagnosis and determine a course of treatment. These tests may also be used to track disease progression over time.

There are generally two kinds of arterial vascular disease: occlusive and aneurysmal. In the occlusive form, blood flow is reduced because of plaque that has formed in the arteries. This causes reduced blood flow to tissues beyond the blockage. In aneurysmal disease, the wall of an artery weakens, which allows it to become larger and rupture is a possibility.

We also consult and manage the venous disease, thoracic outlet syndrome and AV malformations.

What Makes Us Special

The Non-Invasive Diagnostic Vascular Lab at Toronto General Hospital is an Intersocietal Accreditation Commission Vascular Testing (ICAVL) accredited laboratory. We provide excellent quality care using state-of-the-art equipment.

Our staff has extensive experience with advanced non-invasive vascular evaluation in patients with highly complex vascular diseases. We provide a clinical teaching environment to national and international vascular residents.​
