A. T2-weighted MR imaging reveals mild low signal intensity area (arrows) in left peripheral zone at base of prostate. B, C. ADC map (B) demonstrates mild low signal intensity (arrows) and high b-value image (C) demonstrates no high signal intensity at corresponding location (arrows) (A). D. T1-weighted post-contrast image demonstrates early uptake of contrast material (arrows) at corresponding location (A-C). Final PI-RADS assessment was 2. Clinical suspicion persisted and patient underwent MR image targeted biopsy which revealed Gleason 4 + 3 prostate cancer. ADC = apparent diffusion coefficient, PI-RADS = Prostate Imaging Reporting And Data System, PSA = prostate-specific antigen
