Correlation between ADC values and tumor cell density within a tumor region of interest

ADC Parameter Correlation with TCD within a given TROI p value
ADCmean ρ = −0.6164 0.005
ADC10th percentile ρ = −0.5570 0.01
ADCratio ρ = −0.4650 0.04

Note: ADCratio = (tumor ADCmean / NNPT ADCmean), NNPT = non-neoplastic prostate tissue
