Detection of more metabolites in prostate cancer is demonstrated using non-uniformly undersampled (NUS) echo-planar J-resolved spectroscopic imaging (EP-JRESI) data processed using maximum entropy (MaxEnt) non-linear reconstruction method than conventional one-dimensional (1D) MR Spectroscopic imaging (MRSI). We have quantified metabolites changes observed in spermine, myo-inositol and citrate in cancer locations. Based on the ADC values, the diffusion weighted imaging (DWI) was able to differentiate the cancer and non-cancer locations. There were positive and negative correlations between the ADC values and metabolite ratios in cancer locations investigated in our study.
