Additional diagnostic value of lesion visibility on diffusion-weighted imaging for differentiating BI-RADS category 4 MRI-detected breast lesions

Key Points

• To evaluate the additional diagnostic value of lesion visibility on diffusion-weighted imaging for differentiating BI-RADS category 4 breast lesions.
• Analyzed diffusion-weighted imaging (DWI) and MRI data for BI-RADS category 4 lesions.
• Classified lesions as malignant or nonmalignant based on DWI visibility.
• Assessed the correlation between DWI results and biopsy outcomes.
• DWI-negative lesions were primarily associated with nonmalignant findings.
• DWI visibility may help reduce unnecessary breast biopsies by aiding in diagnosis.
