Representative cases. Figure (A-D) shows a 73-year-old man with diffuse LV FDG uptake, who was instructed to fast for a minimum of 6 h and whose FPG and FFA levels were 95 mg/dL and 464 μEq/L at baseline. Cardiac metabolic volume was estimated as 166.4 mL. There are multiple abnormal uptakes in mediastinal and hilar lymph nodes. Figure (E-H) shows a 25-year-old woman without diffuse LV FDG uptake, who had over 18 h’ fasting with a low-carbohydrate diet. Her FPG and FFA levels were 76 mg/dL and 1924 μEq/L at baseline. FDG PET/CT shows focal basal anterior wall uptake. Cardiac metabolic volume was estimated to be 8.3 mL. There are multiple lung uptakes and multiple lymph node uptakes in supraclavicular, mediastinal, hilar, and abdominal regions. MIP = maximum intensity projection
