Ultrasound imaging uses a transducer or probe to generate sound waves and produce pictures of the body's internal structures. It does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that do not show up well on x-ray images. Ultrasound is often used to help diagnose unexplained pain, swelling and infection. It may also be used to provide imaging guidance for needle biopsies or to see and evaluate conditions related to blood flow.

Please arrive 10 minutes prior to your examination. The preparations for an ultrasound vary depending on the body part you are having scanned.

If you are having an ultrasound of any Upper Abdominal Organ (Gall Bladder, Pancreas, Liver, Spleen) and/or Kidney(s) and/or Aorta eat an early low-fat dinner on the night before your exam, and have nothing to eat for 8 hours prior to your exam. Water, Juice, black tea or coffee may be drunk prior to the procedure.

If you are having an ultrasound of your Pelvis you will need to have a full bladder for this exam. Please drink 4 - 6 glasses of liquid. Finish drinking this liquid one hour prior to your exam. DO NOT empty your bladder before the examination.

There is no preparation if you are having an ultrasound of your Thyroid, extremity or other body parts.

You will be asked to lie down on the examination bed. A device, known as a probe, will be used to do the scan. To assist the Ultrasonographer with the scan, a warm gel-like substance will be applied to the skin first. You could be asked to hold your breath during the scan and to roll onto your side.
