Changes in the prostate assessment using classification PI-RADS 2.1

Publication at Faculty of Medicine in Pilsen |


PI-RADS (Prostate Imaging Reporting and Data System) is a structured schematic description of multiparametric magnetic resonance imaging of the prostate in patients suspected of having prostate cancer. The introduction of this classification in 2012 led to more standardized interpretations of findings.

Since then, ratings have been upgraded several times. PI-RADS version 2.1, issued 2019 improved the classification systém and repaired the inconsistencies of previous versions.

PI-RADS version 2.1 uses 5-point scale of risk of carcinoma presence obtained by combining the observed changes in multiparametric examinations in T2w, ADC/DWI and DCE, in each suspicious lesion in the glandular tissue.
