A pelvic ultrasound is a noninvasive diagnostic exam that produces images that are used to assess organs and structures within the female pelvis. A pelvic ultrasound allows quick visualization of the female pelvic organs and structures including the uterus, cervix, vagina, fallopian tubes and ovaries. There can be two parts to your exam: The transabdominal ultrasound and the transvaginal ultrasound. An imaging wand is used for both. Wondering why you need to come for your exam with a full bladder? We use ultrasound waves to recreate images of the internal organs deep within your pelvis. Those waves penetrate liquid or fluid much more easily than they move through air or gas. We use a full bladder like an acoustic window for the ultrasound waves to give us better images of your organs.
