The author reflects on the sensitive and specific use of contrast-enhanced magnetic resonance angiography (MRA) than computed tomography angiography (CTA) or duplex ultrasonography (DUS) for diagnosis of symptomatic lower-limb peripheral arteial disease (PAD). He suggests to consider availability and interobserver variability of specific MRA techniques at each institution and use detailed imaging for intervention. He considers that MRA prevents exposure of patients from ionizing radiation.
