Pelvis

Ultrasound of the Urinary Bladder

Ultrasound is the best means to evaluate the volume of residual urine in the bladder after a patient voids. The volume of the full bladder and the size and configuration of the bladder and prostate can be evaluated.

Ultrasound of the Uterus and Ovaries

Evaluation of the female pelvis was one of the first widespread applications of medical ultrasound technology, and it remains the procedure of choice in imaging this area. The size, texture, and internal architecture of the uterus, its lining (the endometrium) and the ovaries are optimally evaluated with this imaging modality.

Your physician may order this test for numerous reasons, including: pelvic pain, mass, abnormal bleeding, suspected pelvic infection, infertility, follow-up during hormonal treatment, and screening in those with a family history of breast carcinoma. Doppler is utilized in evaluating for abnormal flow in the blood vessels within these structures.

There are two methods in ultrasound evaluation of the female pelvis. Most of the time, both examinations are performed during a single appointment to ensure that a complete view of the pelvis is obtained. There are times, however, when your physician will only order one of these methods. Transabdominal pelvic ultrasound is performed with a full urinary bladder. The urine within the bladder optimizes transmission of the ultrasound signal, thereby allowing better visualization of the uterus and ovaries. This method is best for assessing uterine and ovarian size, shape and position, and for providing an overall view of the pelvis. Transvaginal pelvic ultrasound is performed utilizing a specially designed probe which is placed in the vagina. Transvaginal scanning provides more detailed evaluation of the ovaries and uterus and is usually the best way to evaluate the uterine lining, as well as to obtain “close up” views of ovarian cysts and uterine fibroids.
