Standardization and advancements efforts in breast diffusion-weighted imaging.

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Breast MRI advancements improve cancer detection and characterization.
• Abbreviated MRI protocols offer efficient screening, reducing scan time and cost.
• Diffusion-weighted imaging (DWI) is a promising non-contrast technique for lesion differentiation.

Purpose of the Study:

• To explore the role of breast MRI, particularly DWI and apparent diffusion coefficient (ADC) values, in cancer detection and characterization.
• To discuss the potential of advanced DWI techniques for improved diagnosis.
• To highlight the challenges and ongoing efforts in standardizing DWI protocols and ADC measurements.

Main Methods:

• Review of recent advancements in breast MRI, focusing on abbreviated protocols and DWI.
• Analysis of apparent diffusion coefficient (ADC) values for quantitative lesion characterization.
• Discussion of advanced DWI techniques like Intravoxel Incoherent Motion (IVIM).

Main Results:

• Breast MRI demonstrates high sensitivity for screening and assessing disease extent.
• DWI and ADC values show potential in differentiating malignant from benign breast lesions, reducing biopsies.
• Correlations between ADC values and hormone receptor status exist but show variability.
• Standardization initiatives (EUSOBI, DWIST, QIBA) aim to address measurement variability.

Conclusions:

• Advanced breast MRI techniques, including DWI, significantly enhance breast cancer diagnosis and characterization.
• Standardization of DWI protocols and ADC measurements is critical for reliable clinical application.
• Further research is essential to maximize the potential of breast DWI in patient care.
