Ultrasound technology,although not an absolute measure of cerebral blood flow,uses a noninvasive technique to provide information about the flow velocity of blood through carotid vessels.Carotid duplex studies are used as a routine screening procedure for intraluminal narrowing of the common and internal carotid arteries as a result of atherosclerotic plaques.
