An arterial duplex scan or doppler ultrasound of the upper or lower extremities is used to evaluate the arteries of the extremities with the use of gray scale, color doppler, spectral doppler waveform analysis and segmental limb pressures. With this noninvasive procedure, we can assess the arteries in your leg(s) to identify narrowing of your vessels that may be causing leg pain when walking, resting leg pain, foot, ankle, heel or toe ulcers, or skin discoloration.
What happens during the exam?
The patient lies on a table with the arms or legs covered with a drape or blanket. The sonographer (technologist who performs the exam) will put a warm water-based gel on the skin surface. The gel helps to transmit the sound waves by excluding air. An instrument called a transducer, which is about the size of a microphone, will be moved over the skin surface by the sonographer.
