Doctors Performing an Angiogram
Doctors use angiograms to pinpoint blockages in the heart's blood circulation. An X-ray contrast dye is injected into the coronary arteries, and fast-moving X-ray images are monitored on a screen while the dye flows through the arteries. The procedure is used to help diagnose conditions like myocardial infarction, vascular occlusion, and calcified atherosclerotic plaques.
