The study investigated the feasibility of Diffusion Kurtosis Imaging (DKI) in predicting surgical result upgrading of biopsy-proven Gleason Score (GS) = 6 prostate cancer. The predicting efficiency of clinical variables (tumor volume, PSA level) and MRI variables (ADC, Dapp, Kapp) were compared by ROC analysis. DKI was found feasible to predict surgical result upgrading of biopsy-proven GS = 6 prostate cancer and Dapp-minimun had the highest Az value.
