AOS-111: OB/GYN Sonography I (Spring 2025)
Course Description:
This course will acquaint you with sonographic terms, reference planes, and basic anatomy of the female pelvis in both the gravid and non-gravid states. The identification, interpretation, and documentation of the relevant sonographic images needed to provide correct diagnosis are discussed. Gynecological pathology, fetal development, including complications in the 1st trimester, with their respective sonographic appearance will be emphasized.
Learning Outcomes:
At the completion of this course, you will be able to:
· Identify anatomy, anatomic variants, and sonographic appearances of normal structures of the female pelvis.
o Pelvic muscles
o Pelvic vasculature
o Peritoneal spaces
o Reproductive organs
o Suspensory ligaments
· Demonstrate knowledge of pathology, physiology, pathophysiology, sonographic technique, measurements, sonographic appearances, and Doppler patterns in gynecologic disease processes.
o Inflammatory processes
o Congenital anomalies
o Benign uterine/adnexal masses
o Malignant uterine/adnexal masses
o Contraceptive devices
o Infertility procedures
o Post-partum
· Identify anatomy, anatomic variants, and sonographic appearances of normal maternal, embryonic, and fetal anatomic structures during the first, second, and third trimesters.
