BI-RADS 3: Current and Future Use of Probably Benign

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• The Breast Imaging Reporting and Data System (BI-RADS) category 3 (probably benign) often causes diagnostic uncertainty and patient anxiety.
• Accurate application of BI-RADS 3 is crucial for appropriate patient management and resource allocation in breast imaging.

Purpose of the Study:

• To review the evidence and best practices for utilizing the BI-RADS 3 assessment category across mammography, breast ultrasound, and breast MRI.
• To enhance understanding of the appropriate indications and limitations for employing BI-RADS 3.

Main Methods:

• Review of current literature and guidelines regarding BI-RADS 3.
• Analysis of the 5th edition of the BI-RADS atlas for updated recommendations.
• Evaluation of advanced imaging techniques like data mining, elastography, and diffusion-weighted MRI to improve BI-RADS 3 accuracy.

Main Results:

• Interobserver variability in BI-RADS 3 utilization has been previously identified.
• The 5th edition BI-RADS atlas specifies appropriate use for diagnostic imaging (mammography, ultrasound, MRI) but discourages its use in screening mammography.
• Emerging technologies show promise in refining the accuracy of BI-RADS 3 assessments.

Conclusions:

• BI-RADS 3 is a dynamic assessment category undergoing refinement.
• Appropriate application of BI-RADS 3 can significantly decrease the rate of benign biopsies.
• Judicious use of BI-RADS 3 enables breast imagers to maintain high sensitivity for early-stage breast cancer detection.
