We present the analysis of the utility of mpMRI including quantitative imaging parameters in prostate cancer detection, and the discriminating power of the individual parameters between the biopsy sample pathology-confirmed cancer and non-cancer areas. The multireader setting yielded a high number of additional cancer diagnoses. While for all parameters scores were on average higher for histologically malignant lesions, only T2, ADC500, ADC1400, Subtraction, Ktrans, Ve and TTP showed a significant difference in score.
