Figure 8 This patient had high fluorine-18 fluoro-2-deoxyglucose (FDG) uptake during fasting (a to c) (total uptake score = 33) and a broad, severely reduced region in the lateral wall on the glucose-loading image (d to f) (global percent uptake of injected dose per 100 g tissue 0.54). The findings on the perfusion single-photon emission computed tomography (SPECT) image (g to i) (total defect score = 35) were similar to those on the FDG-positron emission tomography image after glucose loading. Histologic analysis revealed severe fibrosis (Fig. 7c). The patient died of heart failure.
