Ultrasound imaging is a non-invasive, painless test that is performed using a smooth hand-held transducer. The transducer transmits high-frequency sound waves into your body, of which are reflected from different body tissues to produce a real time moving image on a screen.
It is used extensively during pregnancy, and to assess many organs and superficial parts, as well as the heart and blood vessels. Areas of pain, swelling or infection can be directly assessed in real time. Because it’s readily available and cost-effective, it is often the first diagnostic test ordered for abdominal, pelvic and musculoskeletal pain.
