Angiogram

A diagnostic test requiring the insertion of a catheter into an artery or vein through, which dye is injected and x-rays are taken to view the adequacy of the circulation of the vessels viewed. The dye, sometimes referred to as "contrast", does not actually color the blood vessels, but instead blocks x-rays from passing through it, thereby helping to create an image of the artery or vein on an x-ray. Some angiograms are done with still pictures, while others, like heart angiograms, are done using moving pictures.
