Figure 4a:

Scatterplots of ADC versus T2 in NPZ and histologically proved low-grade or high- or intermediate (Int)–grade prostate cancer. Data are shown for (a) all patients (n = 120, 19 low-grade and 54 high- or intermediate-grade lesions) and (b) patients in whom lesions measured on MR images were cognitively targeted during prostate biopsy (n = 43, four low-grade and 22 high- or intermediate-grade lesions). All NPZ regions were measured in NPZ on clinical images and were not sampled for biopsy.
