Ultrasound is an imaging technique that uses sound waves to view soft-tissue organs within the body. The images produced during an ultrasound examination often provide valuable information for diagnosing and treating a variety of diseases and conditions.

Ultrasound imaging involves the use of a small transducer (probe) and ultrasound gel placed directly on the skin. High-frequency sound waves are transmitted from the probe through the gel into the body. The transducer collects the sounds that bounce back and a computer then uses those sound waves to create an image. Ultrasound examinations do not use ionizing radiation (as used in x-rays), thus there is no radiation exposure to the patient. Because ultrasound images are captured in real-time, they can show the structure and movement of the body’s internal organs, as well as blood flowing through blood vessels.
