Breast Diffusion-weighted MR Imaging: Current Applications, Insights from Screening, and Future Directions

Area of Science:

• Radiology and Medical Imaging
• Oncology
• Biomedical Engineering

Background:

• Breast diffusion weighted MR imaging (DWI) is a rapidly advancing non-invasive technique.
• DWI provides valuable information on tissue cellularity and microstructure without contrast agents.
• Its integration into clinical protocols is increasing due to speed and ease of use.

Purpose of the Study:

• To review the principles, acquisition techniques, and clinical applications of breast DWI.
• To evaluate the role of DWI in differentiating benign from malignant breast lesions.
• To explore DWI's potential as a standalone screening tool and in treatment monitoring.

Main Methods:

• Comprehensive literature review of breast DWI studies.
• Analysis of DWI principles and standardization of acquisition protocols.
• Evaluation of clinical evidence for DWI applications in breast imaging.

Main Results:

• DWI aids in distinguishing benign from malignant breast lesions, potentially reducing unnecessary biopsies.
• Evidence supports DWI's utility in assessing treatment response and as a prognostic indicator.
• Emerging DWI techniques show promise for future breast cancer management.

Conclusions:

• Breast DWI is a valuable tool in clinical practice for lesion characterization and treatment assessment.
• Further research into advanced DWI techniques may enhance its role in breast cancer screening and management.
• DWI offers a contrast-free imaging option with significant diagnostic potential.
