Quantitative MR Imaging of the Breast

Area of Science:

• Radiology
• Medical Imaging
• Oncology

Background:

• Breast MRI interpretation traditionally relies on subjective assessment (BI-RADS).
• Quantitative MRI data offers objective imaging biomarkers for enhanced diagnostic accuracy.
• Advances highlight the value of quantitative MRI in breast disease management.

Purpose of the Study:

• To review the role of quantitative MRI in breast cancer diagnosis and management.
• To discuss the potential and limitations of various quantitative MRI techniques.
• To emphasize the need for standardization and validation of quantitative MRI parameters.

Main Methods:

• Review of established quantitative MRI techniques: dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted imaging (DWI).
• Exploration of emerging quantitative MRI approaches: synthetic MRI and fat imaging.
• Discussion of radiomics and background parenchymal enhancement (BPE) in breast MRI research.

Main Results:

• Quantitative MRI, particularly DCE-MRI and DWI, shows promise for objective lesion characterization.
• Reproducibility in quantitative MRI is improving, with changes in apparent diffusion coefficient indicating biological alterations.
• Radiomics and quantitative BPE analysis demonstrate diagnostic and predictive capabilities for breast cancer.

Conclusions:

• Quantitative MRI parameters are crucial for objective breast disease assessment.
• Standardization and validation of quantitative MRI techniques are essential for routine clinical integration.
• Emerging quantitative MRI methods require further research before widespread adoption.
