Representative case of prostate cancer An 80-year-old man with PSA 73.2 ng/mL, PSAD 0.77 ng/mL2, and Gleason score 3 + 4 prostate cancer confirmed after RP. A, B Axial T2WI and FS-T2WI sequences show a T2 hypointense nodule (arrows) involving the left peripheral zone with extraprostatic extension; T2WI score = 5. C Diffusion-weighted image (b = 2000) shows a markedly hyperintense signal (arrows) corresponding to (A) and (B). D ADC map image shows focal hypointense signal corresponding to (C), ADC value of the lesion is 0.829 × 10-3mm2/s; DWI PI-RADS = 5. E Early dynamic contrast enhanced image shows avid enhancement within the anterior lesion (arrows), DCE MRI PI-RADS = positive. PI-RADS score = 5. F, G The Ktrans and Kep values of the anterior lesion are 0.345/min and 1.249/min, respectively. H Gross morphology of the RP specimen. (I) Microscopic pathological view of the index lesion
