BI-RADS: Standardizing Breast Imaging and Reporting

Learning Objectives and CME/Disclosure Information

This activity is intended for healthcare providers delivering care to women and their families.

After completing this activity, the participant should be better able to:

1. List the elements in a standard mammogram report
2. Recall the BI-RADs categories that require a tissue diagnosis

Estimated time to complete activity: 0.25 hours

Faculty:

Susan J. Gross, MD, FRCSC, FACOG, FACMG President and CEO, The ObG Project

Disclosure of Conflicts of Interest

Postgraduate Institute for Medicine (PIM) requires faculty, planners, and others in control of educational content to disclose all their financial relationships with ineligible companies. All identified conflicts of interest (COI) are thoroughly vetted and mitigated according to PIM policy. PIM is committed to providing its learners with high quality accredited continuing education activities and related materials that promote improvements or quality in healthcare and not a specific proprietary business interest of an ineligible company.

The PIM planners and others have nothing to disclose. The OBG Project planners and others have nothing to disclose.

Faculty: Susan J. Gross, MD, receives consulting fees from Cradle Genomics, and has financial interest in The ObG Project, Inc.

WHAT IS IT?

BI-RADS: Breast Imaging Reporting and Data System, was developed by the American College of Radiology (ACR) to standardize mammogram reporting, as well as breast ultrasound and MRI reporting.

The standard mammogram report includes the following

Indication and type of mammogram (screening/diagnostic)
Statement regarding breast density
Description of pertinent findings including size and location, oriented by quadrant and clock position
Summary of important findings and BI-RADS category

KEY POINTS:

BI-RADS Classification Standardizes Findings and Recommendations for Further Management

BI-RADS 0 : Incomplete

Recall for additional imaging/comparison with prior examinations, or both

BI-RADS 1: Negative (Essentially 0% chance of malignancy)

Routine screening

BI-RADS 2: Benign (Essentially 0% likelihood of malignancy)

Routine screening

BI-RADS 3: Probably benign (> 0% but ≤ 2% likelihood of malignancy)

6 month follow-up or continued surveillance

BI-RADS 4: Suspicious (> 2% but < 95% likelihood of malignancy)

4A: Low suspicion for malignancy (> 2% to ≤ 10% likelihood)
4B: Moderate suspicion for malignancy (> 10% to ≤ 50% likelihood)
4C: High suspicion for malignancy (> 50% to < 95% likelihood)
Tissue diagnosis needed for all BI-RADS 4 categories

BI-RADS 5: Highly suggestive of malignancy (95% likelihood of malignancy)

Tissue diagnosis needed

BI-RADS 6: Known, biopsy proven malignancy

Surgical excision when appropriate

Density Categories

Category a: Breasts are almost entirely fatty
- Prevalence: 10% of the population
- Mammography considered highly sensitive in this setting (88%)
Category b: There are scattered areas of fibroglandular density
- Prevalence: 43% of the population
- Still sensitive but decreased from category a (82%)
Category c: Breasts are heterogeneously dense
- Prevalence: 39%
- Small masses may be obscured
- Sensitivity drops to 69%
- Note: Breast cancer risk is 1.2 relative risk compared to average breast density
Category d: Breasts are extremely dense
- Breasts are extremely dense
- Significantly lowers sensitivity of mammography (62%)
- Note: Breast cancer risk is 2.1 relative risk compared to average breast density
