Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high frequency sound waves to produce pictures of the inside of the body. Ultrasound exams do not use ionizing radiation (x-ray). 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.
Ultrasound imaging is usually medical test that helps physicians diagnose and treat medical conditions. Vascular ultrasound provides pictures of the body’s veins and arteries.
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.
