Doppler ultrasonography of an extremity

Doppler ultrasonography of an extremity

Doppler ultrasonography examines the blood flow in the major arteries and veins in the arms and legs with the use of ultrasound (high-frequency sound waves that echo off the body). It may help diagnose a blood clot, venous insufficiency, arterial occlusion (closing), abnormalities in arterial blood flow caused by a narrowing, or trauma to the arteries.
