The purpose of this study was to evaluate the correlation among parameters on CEST imaging by multi pool model, IVIM and 11C-methionine (MET) uptake on PET/CT in gliomas. The maximum values of the parameters on CEST imaging, the minimum parameters (ADC, D, D*) and maximum f on IVIM were measured respectively. 11C-MET uptake was semiquantitatively assessed using tumor-to-contralateral normal brain tissue (T/N) ratio. Several strong correlations were observed among some of the parameters. These preliminary results suggest that parameters on CEST imaging by multi pool model and IVIM seems to correlate with 11C-MET uptake on PET/CT in gliomas.
