The purpose was to investigate the differential features of prostate cancer and prostatitis by 1H MR Spectroscopic Imaging (MRSI)Seventy-two voxels corresponding to the histopathologically confirmed regions of cancer or prostatitis in the peripheral zone were retrospectively evaluated using MRSI. Cancerous voxels were defined as CC/C0.8. The changes in citrate and choline in each voxles were also evaluated. The CC/C for cancer voxels was significantly different from the ratios in the voxles with prostatitis (p<0.05). The overestimation for prostatitis was significantly reduced by adding the requirement that citrate was not or slightly decreased to normal level citrate (Cit/Norm.Cit 0.75).
