MRI-Derived Restriction Spectrum Imaging Cellularity Index is Associated with High Grade Prostate Cancer on Radical Prostatectomy Specimens.

However, when determining the difference in the detection of low-grade and high-grade PCa, a higher RSI z -score was significantly associated with the higher-grade primary Gleason 4 pattern [Odds ratio 10.3 (1.4–78.0; p = 0.02)] and ADC showed a trend in distinguishing between the two Gleason patterns ( p = 0.07) (Table 4 ).
