An arteriogram or angiogram is an x-ray exam of the arteries, which is used to diagnose blockages or other abnormalities of the blood vessels. The objective of the exam is to define the site and extent of the arterial abnormality, allowing the physician to determine the best treatment options, and often allowing the treatment to be performed by the interventional radiologist at the same time.
During this exam, an interventional radiologist inserts a small tube (catheter), which is about the size of the tip of a pencil, through a small nick in the skin into an artery. The radiologist guides the catheter into the artery to be studied by manipulating it while watching on an x-ray monitor, using a fluoroscope. A contrast medium (x-ray dye) is then injected through the catheter while x-rays are taken, to visualize the blood vessels.
