Definition: Vascular ultrasound is a test to see how the blood moves through your arteries and veins. The ultrasound combines traditional ultrasound with Doppler ultrasound. Regular ultrasounds use sound waves that bounce off blood vessels to produce images and doppler ultrasound looks at how the sound waves reflect off moving objects, such as blood. There are different types of vascular ultrasound exams such as carotid doppler, venous doppler of the extremities, and arterial doppler of the extremities.
Alternative names: Doppler ultrasound, duplex studies
