Ultrasound

Ultrasound imaging, also called sonography, involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. Ultrasound exams are safe and non-invasive, and do not use ionizing radiation (X-ray). Since 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. Ultrasound imaging is usually a painless medical test that helps physicians diagnose and treat medical conditions.

Conventional ultrasound displays the images in thin, flat sections of the body. Doppler ultrasound is a special ultrasound technique that evaluates blood as it flows through a blood vessel, including the body’s major arteries and veins in the abdomen, arms, legs and neck.
