DMS 104

Course Description

Prerequisite: DMS 100, DMS 105W, DMS 107, DMS 107L, DMS 108W with a "B" (3.0) grade or better. Concurrent enrollment in DMS 101W DMS 103, and DMS 106W. Discusses various aspects of OB/GYN sonography. Studies normal sectional anatomy and development, fetal assessment, normal and abnormal sonographic patterns, along with techniques and protocols. (30-0)
