To investigate whether Prostate Imaging Reporting And
Data System (PI-RADS) score and Gleason score (GS) are
associated, 298 consecutive biopsy-proven prostate
cancer patients underwent multiparametric magnetic
resonance imaging of the prostate. Each lesion was given
a PI-RADS score and assessed for location, size and
probability of extra-prostatic disease. The highest PI-RADS
score reported for each patient was compared with the GS
of final histology. Patients with a PI-RADS scores of 4
and 5 had respectively more than three and 13-times
higher probabilities of having a GS≥7 than patients with
PI-RADS≤3. The highest PI-RADS score and Gleason score
were strongly associated in our cohort.
