Fig. 1From: Diagnostic accuracy of 13N-ammonia PET, 11C-methionine PET and 18F-fluorodeoxyglucose PET: a comparative study in patients with suspected cerebral gliomaA patient aged 40–45 years with cerebral inflammatory lesion. Contrast enhanced MRI (a) shows the left frontal parietal lobe and adjacent meningeal lesion (arrow) was obvious heterogeneous enhanced. Significant higher uptake of 11C-MET (d) and mild increased uptake of 18F-FDG (b) and 13N-NH3 (c) were observedBack to article page
