Breast Imaging Reporting and Data System v2025: Key Updates in MRI.

Area of Science:

• Radiology
• Medical Imaging

Background:

• The American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) is essential for standardized breast MRI interpretation.
• Previous versions have evolved to improve diagnostic accuracy and reporting consistency.

Purpose of the Study:

• To provide an overview of the key updates in the BI-RADS version 2025 specifically for breast MRI.
• To highlight changes in reporting structure, descriptors, and assessment guidelines.

Main Methods:

• Review of the BI-RADS version 2025 manual focusing on breast MRI sections.
• Analysis of changes related to MRI acquisition, reporting, descriptors, and lymph node evaluation.

Main Results:

• BI-RADS v2025 introduces structured guidance for MRI acquisition and reporting.
• Key updates include descriptor harmonization, T2 signal intensity incorporation, reorganized lymph node assessment, and clarified associated features like peritumoral edema.
• Refined guidance for MRI assessment within a structured clinical indication framework is provided.

Conclusions:

• BI-RADS v2025 offers significant refinements for breast MRI reporting, emphasizing clarity and standardization.
• These updates aim to enhance the consistency and structure of breast MRI interpretation without altering core diagnostic principles.
