Kurtosis model based on Gaussian distribution may be an appropriate condition in prostate. T1rho can detect slow molecular motions of tissue water or proton chemical exchange selectively, which may alter in prostate cancer (PCa). Parameters Dapp, Kapp and T1 relaxation time obtained from T1rho sequence and kurtosis model for DWI underwent statistic analysis between PCa and benign prostate hyperplasia(BPH)patients. Our study showed that Kapp and Dapp could be an effective parameter on PCa detection, while T1rho failed to differentiate PCa and BPH.
