A test most frequently used to confirm cases of stroke, tumor, aneurysm (bulging of the artery walls), a clot, and a narrowing of the arteries and to evaluate the arteries of the head and neck before corrective surgery. It is used to obtain more exact information after an abnormality has been detected by a magnetic resonance imaging (MRI) or computed tomography (CT) scan of the head, such as bleeding within the brain. Under a local anesthetic, a needle is inserted into an artery, usually in the groin area. A catheter is inserted through the needle and then threaded through the main vessels of the abdomen and chest until it is properly placed in the arteries of the neck. The contrast medium is then injected into the neck area through the catheter, and X-ray pictures are taken.
A technique that determines brain death on the basis of whether blood is being circulated to the vital centers of the brain.
Mapping of the cerebral blood vessels using dye and x-rays.
