Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Mass margin | Obscured |
|---|---|
| Mass shape/density | Oval or round, not high density |
| Calcification morphology | Coarse heterogeneous |
| Calcification distribution | Regional |
| Asymmetry | Global asymmetry |
| Architectural distortion | None |
| Suspicious associated features (skin/nipple retraction, skin thickening, axillary adenopathy) | None |
→Suggested categoryBI-RADS 4 (4A–4B)
- Suggested category：BI-RADS 4 (4A–4B): Suspicious (malignancy ~ 2–50%)
- Deciding feature：most suspicious feature → coarse heterogeneous calcifications (also: obscured mass margin, oval/round, not high-density mass)
- Management：Biopsy (image-guided); require imaging-pathology concordance — only then is it benign
| Mass margin | No mass |
|---|---|
| Mass shape/density | Not applicable (no mass) |
| Calcification morphology | No calcifications |
| Calcification distribution | Not applicable (no calcifications) |
| Asymmetry | None |
| Architectural distortion | None |
| Suspicious associated features (skin/nipple retraction, skin thickening, axillary adenopathy) | None |
→Suggested categoryBI-RADS 1
- Suggested category：BI-RADS 1: Negative
- Deciding feature：No abnormal feature entered (negative)
- Management：No abnormal finding: routine screening
Common questions
What is Mammography BI-RADS Structured Read?
Enter mammography findings and get a suggested ACR BI-RADS® v2025 Manual category by 'most suspicious feature decides the category'. Instant, browser-side.
How is Mammography BI-RADS Structured Read calculated? What is the core formula?
Most suspicious feature drives the level: spiculated mass or fine-linear branching calcifications (segmental/linear) or suspicious feature + retraction → 4C–5; → 4; circumscribed mass / focal asymmetry → 3; benign calcifications / fat-containing mass → 2.
When is Mammography BI-RADS Structured Read used?
Structured assistance in assigning a mammography BI-RADS category from descriptors.
What are the key clinical points for Mammography BI-RADS Structured Read?
BI-RADS has no official scoring — the category is set by the most suspicious feature. Associated features (skin/nipple retraction) can upgrade a suspicious finding to 5. v2025 splits category 0 into 'needs additional imaging' and 'needs prior comparison'. The final category must integrate bilateral comparison, prior films and clinical context.
What are the limits and cautions when using Mammography BI-RADS Structured Read?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Mammography BI-RADS Structured Read upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Mammography BI-RADS Structured Read calculated in practice? Can you show a worked example?
