Angiography is term for a range of X-ray tests used to detect and diagnose diseases of the blood vessels, such as weakening of the vessel walls, the narrowing or blocking of vessels, and to examine the chambers of the heart. A very small tube (catheter) is inserted into a blood vessel in your groin or arm. The tip of the tube is positioned either in the heart or at the beginning of the arteries supplying the heart, and a special fluid (called a contrast medium or dye) is injected. The X-ray is taken after the vessels have been injected with a substance (dye) that allows them to be seen on film. The pictures that are obtained are called angiograms.
