Pelvic ultrasound uses sound waves to form pictures of your organs that appear on a screen. It can help your physician assess pain or other symptoms in the pelvis (lower abdomen). For pregnant women, ultrasound is used to check the fetus. The test is done by moving a probe over the abdomen and pelvis. At times, it is also done by placing a probe inside the vagina. This test involves no radiation and is harmless.
