Impact of the clinical ultrasound elective course on retention of anatomical knowledge by second-year medical students in preparation for board exams.

Ultrasound has been integrated into a gross anatomy course taught during the first year at an osteopathic medical school. A clinical ultrasound elective course was developed to continue ultrasound training during the second year of medical school. The purpose of this study was to evaluate the impact of this elective course on the understanding of normal anatomy by second-year students.
