Evaluation of the PI-RADS Scoring System for Classifying mpMRI Findings in Men with Suspicion of Prostate Cancer
Figure 4
Suspicious lesions (arrows) on mpMRI with different PI-RADS sum-scores. Gleason 8 carcinoma: 5 points on T2W for hypointensity and bulging (a), 5 points on DWI for focal very low ADC (b), and 5 points on DCE-MRI for washout curve in a focal lesion (c, d) = sum-score of 15 points. Gleason 7 () carcinoma with 4 points on T2W for focal hypointensity (e), 5 points on DWI for focal very low ADC (f), and 3 points on DCE-MRI for symmetrical washout curve without focal lesion (g, h) = sum-score of 12 points.
