An angiogram is an X-ray procedure used for evaluating blockages in the arterial system. An angiogram detects blockages using X-rays taken during the injection of a contrast agent (iodine dye). The procedure provides information that helps your vascular surgeon determine your best treatment options.
Angiograms are typically performed while you are sedated. The procedure may last 15-20 minutes or up to several hours, depending on how difficult the test is and how much treatment is given.
