Lower Extremity Arterial Ultrasound
Lower extremity arterial ultrasound is a safe and painless way of visualizing the arteries of the legs. It can detect the presence and location of peripheral arterial disease (PAD), narrowing of the arteries supplying the legs. It uses a small hand-held device called a transducer to transmit and receive sound waves. Special equipment changes the sound waves into images that are seen on a monitor. This is the same technology used to image babies in utero (sonogram).
