This study investigates the biophysical basis of clinically observed decrease of ADC in prostate cancer. ADC predicted from gland component partial volumes correlated strongly with measured ADC in both fresh and fixed tissue. Epithelium and lumen partial volumes each correlated more strongly with measured ADC than cellularity metrics: nuclear count and nuclear area. Differences in the partial volume of prostate gland components having distinct diffusivities, rather than changes in the conventionally cited cellularity metrics, are likely to be the major contributor to clinically observed variations of ADC in prostate tissue.
