Ultrasound imaging is a test that uses sound waves to make detailed pictures of your organs. There are three different kinds of ultrasound imaging: abdominal, pelvic, and Doppler ultrasound. Each of these imaging tests can help your healthcare provider assess pain or other symptoms in different parts of your body. Ultrasound does not involve any radiation, and is generally a very safe procedure. Still, you should discuss any concerns with your healthcare provider.
