An X-ray of blood vessels; the person receives an injection of dye to outline the vessels on the X-ray.
An x-ray or computer image (CT scan or MRI) of the blood vessels and blood flow in the body. A dye may be injected through a catheter (small tube) into an artery or vein to make the blood vessels easier to see. An angiogram may be used to check for an aneurysm (a bulge in a blood vessel wall), blockages in arteries, blood clots, or other problems, such as a tumor.
Angiogram has been defined 2 different ways in documents like Glossary of Cancer Terms, NCI Dictionary of Cancer Terms.
