Gynecologic ultrasonography or gynecologic sonography refers to the application of medical ultrasonography to the female pelvic organs (specifically the uterus, the ovaries, and the Fallopian tubes) as well as the bladder, the adnexa, and the Pouch of Douglas. The procedure may lead to other medically relevant findings in the pelvis.
