Ultrasound uses high-frequency sound waves to create real-time images within your body without the use of an X-ray. The images show the structure and movement of your body’s internal organs as well as blood flow. Ultrasound is often used for obstetrics, gynecologic disorders and abdominal, musculoskeletal, and transplant imaging. It is also used for guidance during procedures and surgery.
Preparing for Your Ultrasound
Depending on the ultrasound exam that you will be having, you may need to fast, drink water, take medication or stop medication. Please see the patient instructions for a detailed list for your particular exam.

What to Expect at Your Appointment
The sonographer will position you on a cart inside the exam room. He or she will apply gel to the skin around the area being imaged. The gel helps transmit the sound waves. The sonographer will pass a small, handheld instrument back and forth over the exam area.
Ultrasound Results
A board-certified radiologist reviews your images and provides the results to your ordering provider typically within three business days. Please contact your provider for results. If you are enrolled in MyChart®, you can find your results there as well.
