An arteriogram is a test that allows a doctor to see the arteries on an x-ray. A contrast dye is injected into the arteries to make them visible. The test makes images that can be used to diagnose and treat problems in the arteries.

An arteriogram is done to check the arteries for narrowing, bulging, or blockages. These could be signs of disease.

This test could be done to diagnose conditions such as:

  • Peripheral arterial disease (PAD)—blockages in the arteries in your arms or legs
  • Aneurysm —bulging of the arteries
  • Vascular malformation—problems in the structure of the arteries

Sometimes, the doctor may treat problems found during the arteriogram. The doctor may dissolve a clot or do angioplasty with or without stenting.
