Radiologist

Radiologists are doctors who do imaging tests, like X-rays, ultrasounds, and MRIs. They may also supervise people who perform tests like barium enemas or CT scans.

• Diagnostic radiologists diagnose diseases. They look at the test results and report findings to your other doctors.
• Interventional radiologists treat diseases. They use imaging tests to guide catheters inside the body. Catheters can deliver stents to unblock tubes or blood vessels. They can also place medicine directly into specific areas, such as tumours.

Radiologists who specialize in either diagnostic radiology or interventional radiology are certified by the Royal College of Physicians and Surgeons of Canada.
