Hemodynamics of arterial stenosis,to the brain and eye, and 2) a reduction in hemispheric flow. The purpose of this chapter is to understand the local Doppler velocity signals and the local pressure-flow relationships associated with stenosis of the carotid arteries in order to quantitate the degree of carotid narrowing and its effect on brain perfusion.

Cranial blood flow measurement by means of Doppler ultrasound,rising. The cross-sectional area, by which mean velocity must be multiplicated to compute volume flow, is either calculated from the internal vessel diameter, as measured with the impulse echo technique or by moving a single gate across the vessel for detecting the borders of the blood column from the Doppler signal .

Vascular bruits, is therefore important that the noninvasive examinations for cerebrovascular abnormalities begin with a careful auscultation of the head, neck, and chest in order to guide the examination to assure localization of the source.

Transcranial Doppler diagnosis,bital or transforamenal approaches also exploits gaps or thin regions in the cranial bone structures to obtain Doppler signals from intracranial arteries proximal to the circle of Willis. The purpose of this chapter is to describe the transcranial Doppler method and its use for diagnosis of cerebrovascular disease.
