The angiographic catheter is a piece of equipment that doctors use to inject and withdraw contrast media into and from the arteries. The contrast media helps the doctor see the arteries in X-rays. The catheter is inserted through an artery in the groin, arm, or neck. A catheter may be used when you need to have an angiogram (X-ray examination) or arteriogram (X-ray examination of the arteries).
Your doctor may use an angiographic catheter to inject contrast media into one or more blood vessels so that he or she can take pictures of the inside of your body using X-rays or CT scans.
