Overview of Various Noninvasive Cerebrovascular Techniquess and complications played a great role in the drive to develop accurate, reliable noninvasive diagnostic procedures. Although arteriography serves to define anatomic lesions and is indispensable for most vascular surgery, it provides little objective data regarding physiologic disability, nor is it

Duplex Scanning of the Carotid Arteriesth more widespread utilization of direct methods of diagnosis. Of these, duplex scanning has achieved major prominence. In this time, a technology that was initially highly experimental has achieved clinical maturity with validation of its application by many comparative studies. An appreciation of

Vertebral Artery Ultrasonographybrobasilar disease remain undiagnosed or diagnosed incorrectly. Some common symptoms, such as dizziness or transient loss of consciousness, do not always prompt detailed examination of the posterior circulation vessels.

Transcranial Doppler Sonographye major branches of the Circle of Willis through the intact skull.. A 2-MHz frequency pulse wave ultrasonic beam penetrates the skull and allows returned echo signals to be detected. The frequency shift of the returned echoes is calculated using the Doppler equation . . = 2 . . . cosθ/(. − cosθ), wh

Duplex Ultrasound in the Diagnosis of Temporal Arteritis0.. Giant cell arteritis can be subclassified into at least three main types: cranial, affecting the arteries of the face, head, and posterior cerebral circulation; large vessel, involving the axillary and subclavian arteries; and aortic, leading to aneurysmal degeneration of the ascending aorta or
