A cerebral angiogram allows radiographic (or x-ray) examination of the cerebral vasculature for suspected abnormality and should accompany other tests before final diagnosis. PURPOSE: To detect cerebrovascular abnormalities and to study vascular displacement. PROCEDURE: While supine on a radiographic table, the patient will receive injections of contrast medium into the femoral, carotid, or brachial artery, followed by a series of X-rays that record vascular status. NORMAL FINDINGS: X-rays show normal blood flow to the brain and cerebral vasculature appears symmetrical. ABNORMAL FINDINGS: Cerebral angiograms may detect an aneurysm, arteriovenous malformation, thrombosis, stenosis, or occlusion. It may also identify vascular changes or displacement caused by tumor, hematoma, cyst, edema, herniation, arterial spasm, intracranial pressure or hydrocephalus. |
