What is a leg ultrasound?

A leg ultrasound is a noninvasive test which uses high-frequency sound waves in order to produce an image that shows continuous blood flow through an artery or vein. Determining the amount of blood flow in an artery or vein is important in establishing whether or not there is a clot or other obstruction or abnormality found.

A leg ultrasound, which can also be referred to as a Doppler ultrasound or a sonogram, is completely painless for a patient, making it a valuable and commonly used tool within the medical field.

Why may I need a leg ultrasound?

Leg ultrasounds are particularly good at finding arteries that are narrowed or hardened, limiting blood flow to the legs and feet. Dr. Jain may perform a leg ultrasound if he sees leg swelling, suspects an arterial blockage or blood clot, an injury to a blood vessel, or a vascular tumor in your leg.
