A peripheral arterial duplex ultrasound examines blood flow in the arteries of the legs and abdomen. It combines traditional ultrasound with Doppler imaging to detect narrowing or blockages caused by plaque or calcium buildup.
This test is used to evaluate:
- Peripheral arterial disease (PAD)
- Leg pain with walking (claudication)
- Cold feet or weak pulses in the legs
- Ulcers or wounds that aren’t healing
It helps identify poor circulation that may require treatment with medication, angioplasty, or stenting to restore blood flow.
