Cerebral Angiography

Cerebral angiography is a process that determines any blood vessel abnormalities in the brain like localized swelling in the wall of the arteries, atherosclerosis, and other conditions. During cerebral angiography, a catheter is inserted into the blood vessel through a small incision with the help of x-ray guidance. Then a contrast is injected through the catheter, and when the contrast medium reaches the blood vessels that need to be examined, multiple x-rays are taken. The test is usually done under general anesthesia.
