Synopsis

PSMs are an independent risk factor for biochemical recurrence in patients after radical prostatectomy. DKI quantifies the non-Gaussian nature of the real water molecule diffusion, and accurately reveals the changes in the microstructure of the tissue. Results of this study indicate that MD, Da , Dr, MK, Ka and Kr can be used to predict predicts positive margins after radical resection of localized prostate cancer.
