Duplex sonography is still regarded as the first-choice imaging technique for the work-up of diabetic patients with suspected peripheral artery disease. Should additional information be required prior to digital subtraction angiography (DSA), computed tomography angiography (CTA) or magnetic resonance angiography (MRA) can be performed. The article has outlined in a comprehensive manner both the advantages and shortcomings of these techniques. DSA, an invasive technique, is still considered the gold standard, offering the highest spatial resolution and image quality, in addition to the possibility of performing endovascular revascularization of the limb within the same session.
