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 recto-uterine pouch.

The procedure may lead to other medically relevant findings in the pelvis.This technique is useful to detect myomas or mullerian malformations.

The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically designed vaginal transducer.

Scans are performed by health care professionals called sonographers, or gynecologists trained in ultrasound.

A review in 2015 came to the conclusion that SIS is highly sensitive in the detection of intrauterine abnormalities in subfertile women, comparable to hysteroscopy.
