A comprehensive diagnostic protocol integrating DWI-ADC value and dynamic contrast enhancement (DCE) MR mammography was developed to evaluate the breast diseases. It improved both the sensitivity and specificity of the prediction when compared to DCE only. The ACR BI-RADS categories based on the comprehensive diagnostic protocol were well correlated with the pathological grades.
