Arterial Duplex Scan (one or both legs)

An arterial duplex ultrasound is a non-invasive imaging procedure that uses high-frequency sound waves to produce images of structures in the body. The ultrasound uses two modes of ultrasound imaging: one to see the structures of your arteries, the other to see the speed and direction of blood flow in those arteries. This procedure is often done to identify peripheral artery disease (PAD).
