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.
