Introduction to Neurologic and Vascular Sonography

DMS 201

Course Description

Prerequisites: Prerequisites: DMS 112, DMS 113, DMS 114, DMS 115, DMS 116, and DMS 117 each with a "B" (3.

0) minimum grade. Concurrent enrollment in DMS 202, DMS 206, DMS 207, LWA 206B, and LWA 206C. Provides an overview of sonographic imaging of the neonatal and infant brain. Includes normal and abnormal anatomy and sonographic patterns. Looks at basic vascular ultrasound with emphasis on normal anatomy, imaging techniques, and basic pathology. (45-0)
