Arterial imaging in patients with lower-extremity ischemia and diabetes mellitus.
Precise comprehensive imaging of arterial circulation is the cornerstone of successful revascularization of the ischemic extremity in patients with diabetes mellitus. Arterial imaging is challenging in these patients because the disease is often multisegmental, with a predilection for the distal tibial and peroneal arteries. Occlusive lesions and the arterial wall itself are often calcified, and patients with ischemic complications frequently have underlying renal insufficiency. Intra-arterial digital subtraction angiography, contrast-enhanced magnetic resonance angiography, and, more recently, computed tomographic angiography have been used as imaging modalities in lower-extremity ischemia. Each modality has specific advantages and shortcomings in this patient population, which are summarized and contrasted in this review.
