We used T₂, T₂*, and T₂ maps to assess critical limb ischemia (CLI) using MRI. Neither T₂* nor T₂ were found to be able to discriminate patients with severe ischemia from normal controls. However, T₂-values differed significantly (P=0.011, CI95=[5.6;29.7]) between patients (T₂=57.4 7.9 ms) and controls (T₂=39.7 3.3 ms). The observed difference is attributed to increased edema in patients suffering from CLI.
