An angiogram is an x-ray picture of your blood vessels obtained
by injecting contrast or "dye" into the vessel using a catheter. The
catheter is introduced into the artery by needle access with local
anesthesia, usually in the upper leg.
There are many types of angiograms. Depending on your problem, we may be
looking at the blood vessels in your legs, abdomen, chest, neck, head or
arms. Regardless of the actual vessels being studied, most angiograms
are performed in a similar fashion.
