Diffusion-weighted imaging of suspicious (BI-RADS 4) breast lesions: stratification based on histopathology.

Objective: To test the use of diffusion-weighted imaging (DWI) in stratifying suspicious breast lesions (BI-RADS 4), correlating them with histopathology. We also investigated the performance of DWI related to the main enhancement patterns (mass and non-mass) and tested its reproducibility.

Materials And Methods: Seventy-six patients presented 92 lesions during the sampling period.
