An image obtained using a radiographic technique, which involves the injection of a radio-opaque (shows up on X-ray) contrast material into a blood vessel for the purpose of identifying its anatomy on X-ray. This technique is used to image arteries in the brain, heart, kidneys, gastrointestinal tract, aorta, neck (carotids), chest, limbs and pulmonary circuit. Angiograms are used in cardiac catheterization, a procedure that involves the injection of the contrast material into the coronary arteries through a thin tube inserted in the arm or groin area.
