1-25 kg/m2; group III, 25.1-30 kg/m2; and group IV, 30.1-35 kg/m2) for comparison. A P value of less than 0.05 was considered significant. Results In total, 109 patients underwent 18F-FDG PET/CT studies after injection of different amounts of 18F-FDG radioactivity and a mean uptake time of 62.32 min. The mean NECRglobal and IQglobal for each group were significantly different from other groups (P 0.05). NECRlocal and IQlocal correlated moderately (r = 0.64). Conclusion Optimization of injected 18F-FDG radioacti
