What is a transvaginal ultrasound?
A transvaginal ultrasound is a technique used to image the female reproductive organs and surrounding pelvic structures. This includes your cervix, uterus, ovaries, and the fetus. The transducer is placed inside the vagina to attempt better visualization of these structures or the fetus. There is no special preparation for the transvaginal ultrasound. Although a transvaginal ultrasound is not performed at every appointment, it may be necessary to provide the physician with more information on the baby, your cervix, or the placental location.
