Coronary CT scan

A coronary CT scan is often used by doctors to refine a diagnosis. This test involves taking pictures of the coronary arteries, heart muscle and aorta to identify narrowed arteries or congenital abnormalities. UZ Brussel has special expertise in this area and has the latest new scanner in the sector.

Before the test

  • You must not eat or drink anything for three hours before the test.
  • The referring cardiologist/doctor will usually prescribe a beta blocker (Bisoprolol 5 mg or other) to take once only on the day of the test. This is done to slow the heart rate because it improves the quality of the three-dimensional images of the heart that are taken.
  • This test is not recommended for patients with a proven contrast allergy or during pregnancy.

The test

  1. Before the test a drip will be placed in your arm. This makes it possible to administer a contrast fluid during the test.
  2. A high-quality scanner, which uses X-rays is then used to take pictures of the heart and blood vessels.
  3. During this scan you will be asked to hold your breath for a moment.

After the test

  • After the test you must stay in the waiting room for a further half an hour until the contrast product has passed through the body.
  • After 24 hours the results will be sent to the doctor who requested the test.
