Abstract:

Objective To evaluate the diagnostic value of positron emission tomography/computed tomography (PET/CT) imaging with different radionuclide agents in the diagnosis of gliomas.Methods Diagnostic clinical trials of different imaging agents for gliomas were searched in the Chinese and English language databases. Original data like the true positive, false positive, true negative and false negative were extracted from eligible literatures. Meta - Discl 1.4 was used data analysis. The sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under SROC curve (AUC) of PET/CT imaging using different imaging agents in the diagnosis of glioma were calculated. Results A total of 14 eligible literatures were included, involving 9 describing 18F-fluorodeoxyglucos (18F-FDG) imaging, 8 describing 11C-Methionine (11C-MET) imaging, 3 describing 18F-fluoro-ethyl-L-tyrosine (18F-FET) imaging, 1 describing 13N-NH3 imaging, and 1 describing O-(2-18F-fluoroethyl)-L-tyrosine (18F-FLT) imaging. The data of 18F-FDG, 11C-MET and 18F-FET were analyzed and compared. The results showed that the SEN and diagnostic performance (AUC value) of 11C-MET and 18F-FET PET/CT for gliomas were significantly higher than those of 18F-FDG (P<0.05). However, there were no significant differences in SPE, PLR, NLR and DOR between groups (P>0.05). Conclusion 11C-MET and 18F-FET PET/CT imaging are superior to 18F-FDG PET/CT imaging in the diagnosis of gliomas.
