FIGURE 1. Short-axis views of ¹⁸F-FDG PET (A) and ²⁰¹Tl SPECT scintigraphy (B) of 50-y-old patient with significant stenosis of circumflex artery with moderately decreased global LV function. Perfusion/metabolism mismatch is present in midlateral wall with reduced ²⁰¹Tl uptake and increased ¹⁸F-FDG uptake. Electrical activity (unipolar voltage) was nearly normal in all segments (C), whereas LLS showed decreased values in midlateral wall (D).
