Angiogram
An angiogram is an x-ray taken of an artery after the artery has been injected with a contrasting material that can be seen on the x-ray. For example a coronary artery is one that is commonly done to test for coronary artery disease, the exact location of the blockage, the amount of the blockage and other details to decide on the treatment. The angiogram is an invasive procedure that involves some dangerous risks, but the risk is only one in a hundred and may be worth it. Any person considering an angiogram should be given a thorough analysis of the procedure with the risks and benefits to make the appropriate decision. The test is made with a local anesthesia and is done by inserting a small catheter in an artery in the arm or groin which is guided by an instrument to the opening of the coronary arteries. Then a small amount of the contrasting material is injected into each artery. The x-rays produced are the angiogram.
The x-rays produced are the basis by which the doctor diagnoses the extent of the disease and the most favorable treatment which includes many options.
