Diagnostic Value of PET Tracers in Differentiating Glioma Tumor Recurrence from Treatment-Related Changes: A Systematic Review and Meta-Analysis

Amino acid-based tracers exhibited the highest diagnostic value in identifying TRC and TP in gliomas, with ¹¹C-MET and ¹⁸F-FDOPA having the most notable advantages. Research on other new tracers is limited, therefore, further studies are needed to prove their diagnostic value.
