Vaginal ultrasonography
(重定向自Transvaginal ultrasound)
Vaginal ultrasonography is medical ultrasonography by applying 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.
