What is Ultrasound

General ultrasound is a diagnostic imaging examination that uses high-frequency sound waves to produce real-time images of organs, soft tissues, blood vessels, and other structures within the body. Unlike X-rays, ultrasound does not use ionizing radiation.

Ultrasound examinations are commonly used to investigate symptoms, monitor medical conditions, guide treatment decisions, and evaluate the structure and function of internal organs. Examinations are performed by a qualified sonographer and interpreted by a radiologist. A report is sent to your referring healthcare provider.
