Arteriography , often called coronary angiography, is a testing procedure in which dye visible by X-ray is injected into the bloodstream. Then X-ray pictures are taken and studied to see if the arteries are damaged.
Coronary arteriography is used to evaluate blockages in the arteries that supply blood to the heart.
It's an important tool that helps doctors evaluate the number and severity of diseased coronary arteries. It isn't possible to discuss the pros and cons of coronary arteriography, because it's different for every patient. The physician and patient should discuss this on an individual basis. In general, when performed by experienced physicians in hospital-based laboratories, the procedure is very safe. The information gained helps the physician select the optimal treatment for the patient.
