SON 2171 - Vascular Sonography 1 SON 2171 - Vascular Sonography 1 This course focuses on the theory, rationale, application, performance and interpretation of Carotid Duplex and Transcranial Ultrasound. Anatomy and physiology of the extracranial and intracranial vessels will be discussed. Pathological changes that occur during disease processes will be emphasized. Normal and abnormal color flow and spectral Doppler flow patterns will be discussed. Emphasis will be placed on normal and abnormal velocities and their relevance. An introduction to surgical treatments will be included. The student develops the skills necessary to perform diagnostic ultrasound studies for presentation to the physician. The student reviews the physics and instrumentation of Doppler ultrasound; learns normal hemodynamics and hemodynamics present in disease states; and learns protocols and diagnostic criteria related to cerebrovascular testing.
