Ultrasound - Pelvic
For women, pelvic ultrasound is most often used to examine the uterus and ovaries, and during pregnancy, to monitor the health and development of the embryo. In males, a pelvic ultrasound usually focuses on the bladder and the prostate gland.
For females, pelvic ultrasound examinations can help determine the causes of pelvic pain, abnormal bleeding, or other menstrual problems. Ultrasound images can also help to identify and assess cysts and fibroid growths as well as ovarian or uterine cancers. Other indications include evaluation of the uterine cavity looking for birth anomalies or scars. Female pelvic ultrasound is also used to monitor and assess the development of follicles in patients undergoing fertility treatment.
Sometimes the radiologist may determine that a transvaginal scan needs to be performed. Instead of a transducer being moved across the abdomen, the high-frequency waves are emitted by a probe (endovaginal transducer) placed in the vagina. This technique often provides improved images of the uterus and ovaries, and can be especially useful in early pregnancy.
For males, pelvic ultrasound is a valuable tool for evaluating the prostate gland, as well as the tubes that carry semen.
In both sexes, pelvic ultrasound can help to identify tumors and other disorders in the urinary bladder. The pelvis houses some of the largest blood vessels in the body, and ultrasound can be used to evaluate blood flow in these vessels.
