The purpose of this study was to investigate the
distribution of diffusion coefficients in prostate
cancer (PC) and healthy peripheral zone (PZ) using the
statistical model based on a gamma distribution.
Twenty-six patients with PC were included in this study.
The mean and the standard deviation were significantly
lower in PC than in PZ. ADC < 1.0 (%) was significantly
higher in PC than in PZ and ADC > 3.0 (%) was
significantly lower in PC than in PZ. The statistical
model provides additional insight for DWI and allows us
better correlation of diffusion signal decay and
