Cerebral angiography is a study of the blood circulation of the brain.
It is performed under local anaesthesia. An injection of contrast material through this catheter renders the study of the brain's circulation possible. If the exam is done before noon, fasting after midnight is required. If the exam is scheduled for after 12 noon, a light breakfast may be taken. The test is performed by a radiologist, assisted by trained nurses and X-ray technologists.
