Why is the Test Performed?
The test is most frequently used to confirm cases of stroke, tumor, bulging of the artery walls, a clot, a narrowing of the arteries, and to evaluate the arteries of the head and neck before a corrective surgery. It is used to get more exact information after something abnormal has been detected by an MRI or CT scan of the head such as bleeding within the brain.
