Angiography

Angiography is a special X-ray procedure that takes pictures of your blood vessels. Angiography is performed to image and diagnose diseases of the blood vessels in the body. An interventional radiologist places a catheter, which is a small tube, into one of your arteries and injects contrast (dye) into the vessels while taking X-rays of this area. Angiography is now used to guide balloon angioplasty catheters and stents that stretch the walls of a narrowed blood vessel, restoring normal blood flow without surgery.
