Obstetric and Gynecologic Sonography
Test Questions
Course Introduction
Obstetric and Gynecologic Sonography is a course designed to provide students with a comprehensive understanding of ultrasound techniques as applied to the female reproductive system and pregnancy. The course covers the principles and instrumentation of ultrasonography, fetal development and anatomy, assessment of gestational age, detection of fetal anomalies, and monitoring of maternal and fetal health throughout pregnancy. Additionally, students learn to identify normal and pathological conditions of the uterus and ovaries, including tumors, cysts, and other gynecologic disorders. Practical components emphasize image acquisition, interpretation, and reporting to prepare students for clinical practice in diagnostic medical sonography.
