Ultrasound uses high-frequency sound waves to create images of the internal structures of the pelvis. A transabdominal ultrasound involves scanning over the lower abdomen, while a transvaginal ultrasound involves inserting a probe into the vagina for closer and clearer images. Ultrasound is often the first-line imaging study for evaluating pelvic pain, abnormal bleeding, and assessing ovarian and uterine health.
