Evaluation of the PI-RADS Scoring System for Classifying mpMRI Findings in Men with Suspicion of Prostate Cancer

Table 6

Recommendation to calculate an overall PI-RADS score, based on division from the sum-score, with tumor incidences derived from our data.

Overall PI-RADS scoreSum-score of T2W, DWI, and DCE-MRINumber of patients (%)Tumor incidence (% of biopsies)Definition of the ESUR panel

13, 41 (1%)Clinically significant disease highly unlikely to be present
25, 6, 759 (41%)11%Clinically significant cancer unlikely to be present
38-936 (25%)19% Clinically significant cancer is equivocal
410–1231 (22%)65% Clinically significant cancer likely to be present
513–1516 (11%)94% Clinically significant cancer highly likely to be present

Changes in comparison to the system of Röthke et al. [13] are underlined (threshold between PI-RADS 2 and 3).
