The catheter can be advanced into the coronary arteries and a dye injected into the arteries (coronary angiography or arteriography). With the use of fluoroscopy (a special type of X-ray), the doctor can identify blockages in the coronary arteries as the dye moves through them.

The dye will let your doctor see whether you have blockages in a main artery or its branches. This information is recorded on a television monitor.
