An arteriogram (also called an angiogram) is a diagnostic test in which a contrast dye is injected into one of the arteries so that a road map of your vessels can be seen. An arteriogram provides an X-ray image of the blood vessels so that your doctor can evaluate various vascular conditions such as an aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel) or blockages. The test can show if and where arteries are blocked.

Preparation for the procedure

Food and fluid are restricted 6 to 8 hours before the test. The procedure takes place in the hospital, either in the Department of Radiology or the Cardiovascular Unit, and you will be asked to wear a hospital gown. Sometimes admission the night before the test is required, otherwise you will be admitted as an outpatient or an inpatient the morning of the procedure.

Your doctor will explain the procedure and its risks. A witnessed, signed consent for the procedure is required.

Tell your doctor if you:

  • Have had a bad reaction to contrast material (dye) in the past
  • Are taking Viagra
  • If you might be pregnant
