It is important to distinguish between tumor recurrence and treatment effects in posttreatment patients with high‐grade gliomas. Several imaging modalities have been reported in differentiating between tumor recurrence and treatment effects. However, there were no consistent conclusions between different studies. We performed a meta‐analysis of 23 studies that compared the diagnostic values of fluorine‐18‐fluorodeoxyglucose ( 18 F‐FDG ) and 11 C ‐methionine ( 11 C‐MET ) PET (positron emission tomography) or PET/CT (computed tomography) and magnetic resonance spectroscopy ( MRS ) in predicting tumor recurrence of gliomas. The pooled estimated sensitivity, specificity, positive likelihood ratios, negative likelihood ratios and summary receiver operating characteristic curves of 18 F‐FDG and 11 C‐MET PET or PET/CT and MRS in detecting tumor recurrence were calculated. In conclusion, MRS is highly sensitive in the detection of tumor recurrence in glioma. 18 F‐FDG PET or PET/CT is highly specific in recurrence diagnosis. 11 C‐MET does not have noticeable advantage over 18 F‐FDG . The current evidence shows no statistical difference between MRS and PET on the accuracy.
