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.
Coronary Angiography: Coronary angiography is an X-ray examination of the blood vessels or chambers
of the heart.
Peripheral Angiography: An angiography procedure to detect fatty deposits in the inner linings
of the artery walls is called a Peripheral Angiography.
Carotid Angiography: This X-ray procedure detects the presence of fatty deposits in the Carotid
Artery which carries blood to the brain.
