Ultrasound imaging, also called ultrasound scanning or sonography, involves producing images of the body using high frequency sound waves. Ultrasound examinations do not use ionizing radiation (as used in x-rays), and do not cause any known harm.
Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs.
You will be asked to lie on a couch and a water based gel is placed on to the skin. A small hand held probe called a transducer is then moved over the skin.
