The total patient sample comprised of n=180 patients, who received either HBB, ME, were instructed to adhere to DR, or received a combination of those measures prior to the MR scan. Magnetic Resonance Imaging (MRI) is a method of scanning used to visualize detailed internal structure and limited function of the body. ShapiroWilk test was used to assess the distribution of data. MRI requires specialized equipment to allow evaluation of the prostate with detail that is not available with other imaging methods. A p value of<0.05 was considered statistically significant. Apparent diffusion coefficient (ADC) parametric maps were calculated using a monoexponential fit based on three obtained b-values (100, 600, 1000s/mm2).
