These authors compared the diagnostic accuracy of PET with that of CT and MRI in the diagnosis of recurrent glioma in 26 previously published articles. PET studies with either FDG or carbon methionine were obtained once glioma recurrence was suspected on CT and/or MRI. Diagnostic accuracies were heterogeneous and studies did not compare PET with other imaging modalities. Despite these limitations, PET with both tracers appears to have a moderately good accuracy as an add-on test for diagnosing recurrent glioma.
