Diffusion-weighted imaging improves the diagnostic accuracy of conventional 3.0-T breast MR imaging.

Purpose: To evaluate the incremental value of diffusion-weighted (DW) imaging and apparent diffusion coefficient (ADC) mapping in relation to conventional breast magnetic resonance (MR) imaging in the characterization of benign versus malignant breast lesions at 3.0 T.

Materials And Methods: This retrospective HIPAA-compliant study was approved by the institutional review board, with the requirement for informed patient consent waived.
