Vaginal ultrasonography

Vaginal ultrasonography is a medical ultrasonography that applies an ultrasound transducer (or "probe") in the vagina to visualize organs within the pelvic cavity.

It is also called transvaginal ultrasonography because the ultrasound waves go across the vaginal wall to study tissues beyond it.

It is preferred over abdominal ultrasonography in the diagnosis of ectopic pregnancy.

[3] If a patient had a prior endometrial sampling that was inconclusive, then a transvaginal ultrasound can be used to triage a woman with post-menopausal bleeding.
