Supplemental Figure 1. Patterns of fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) scans. A: No abnormal FDG uptake. B: Diffuse FDG uptake in the left ventricular wall, which could either signify diffuse sarcoid activity or an inadequate dietary preparation. C: Patchy FDG uptake in the septum of the left ventricle. D: Patchy uptake in the lateral left ventricular wall on top of mild diffuse uptake in the left ventricle. Of note, “patchy” and “patchy on diffuse” patterns are more specific for cardiac sarcoidosis. E: Abnormal right ventricular FDG uptake. F: Poor preparation with nonspecific uptake throughout.
