Diagnostic performance of prostate imaging reporting and data system v2.1: Single center experience

Abstract

Aim: To assess the diagnostic accuracy of PI-RADS v2.1 using multi-parametric magnetic resonance imaging (mpMRI) to detectprostate cancer (pCa) and comparison with transrectal biopsy/radical prostatectomy results.Material and Methods: Between June 2017 and April 2019, 124 patients who underwent mpMRI prior to transrectal biopsy/ radicalprostatectomy were evaluated by a pathology results-blinded uroradiologist using PI-RADS v2.1 categories, retrospectively. PIRADSv2.1 category results were compared with transrectal biopsy/radical prostatectomy results. All clinical data were used in statisticalanalysis.Results: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy values of mpMRI using PI-RADSv2.1 categorization were 96%, 44%, 73%, 88% and 75%, respectively. A significant correlation was observed between a high PI-RADSscore and high pathological grade (p
