Over the past decade, noninvasive imaging of the peripheral arteries has evolved into a highly reliable alternative to invasive digital subtraction angiography. Both magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are capable of identifying the location and grade of peripheral arterial disease (PAD) with high accuracy, and both modalities can be used to manage the entire spectrum of patients with suspected or known PAD. Although atherosclerotic PAD is the underlying cause of symptoms in the vast majority of patients, noninvasive cross-sectional imaging is also well suited for identification of alternative non-atherosclerotic causes such as vasculitis and other less frequent causes.
