Patients

This retrospective study was HIPAA compliant and approved by the local Institutional Review Board. With the help of our institutional search engine, we identified patients who underwent endorectal coil mpMRI at 3T between January 2011–January 2015, were treatment naïve, and had pathologically proven PC within 6 months of mpMRI. Prior to the radiologist reviewing the cases, the mpMRIs underwent pre-screening to exclude cases that did not have high b-value (at least 0, 1400 s/mm²) DWI imaging.
