Graph (a) showing tracer uptake ratios in tumors and NNL. *P < 0.001. b ROC curve analysis of L/WM ratio to differentiate between tumors and NNL (NH3: AUC, 0.819; optimal cutoff, 1.92; MET: AUC, 0.840; optimal cutoff, 1.97). Graph (c) showing the correlation between tracer uptake and glioma grade. *P < 0.001. d ROC curve analysis of L/WM ratio to differentiate between HGG and LGG. Area under curve (AUC) was 0.964 for FDG (optimal cutoff, 1.65), 0.896 for NH3 (optimal cutoff, 2.01) and 0.928 for MET (optimal cutoff, 2.74)
