The course objective is to provide instruction regarding the identification of sonographic anatomy and the sonographic applications for obtaining diagnostic images of the intracranial and extracranial components of the cerebrovascular system. The lecture portion includes an introduction on 2-D, PW (Pulse Wave) Doppler, and Color Flow imaging in conjunction with vascular calculations for evaluation. The laboratory portion includes extensive practice of 2-D (2-dimensional) and Doppler cerebrovascular protocols. Instrumentation, scan planes, hemodynamics, calculations, and sonographic pathology of the cerebrovascular system will be covered.
