Cerebral Angiography

— A procedure used most frequently to confirm cases of stroke, tumor,bulging of the artery walls (aneurysm), a clot or narrowing of the arteries and to evaluate thearteries of the head and neck before surgery. It is used to get more exact information aftersomething abnormal, such as bleeding within the brain, has been detected by an MRI or CTscan of the head. The arteries are not normally seen in an X-ray, so a contrast dye is injected into one or more arteries to make them visible. For the cerebral angiography, the dye is injectedinto one or both of the carotid, or vertebral, arteries in the neck (leading to the brain). (Alsoknown as carotid angiography, vertebral angiogram and head angiography.)
