Central Illustration. SPECT/CT perfusion imaging of perfusion response to lower extremity revascularization in the setting of DM and CLI.

Central Illustration.

Pictured is (A) a patient who demonstrated a low perfusion response to revascularization (i.e. 5%) and underwent eventual minor amputation in the first month, and (B) a patient who alternatively demonstrated a high perfusion response (i.e. 29%) and did not receive an amputation in the 12 months after revascularization.
