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.
| Internal echogenicity | Isoechoic |
|---|---|
| Shape | Round |
| Orientation | Parallel (aspect ratio < 1) |
| Margin | Angular |
| Posterior features | Posterior enhancement |
| Calcifications | Benign calcifications (coarse/rim/round, etc.) |
| Associated features | None |
→Suggested categoryBI-RADS 4 (around 4A–4B)
- Suspicious features：margin angular (1 total)
- Suggested category：BI-RADS 4 (around 4A–4B) — any suspicious feature places it in category 4 needing biopsy; more/more typical features raise the category
- Management：Suspicious: biopsy; a single suspicious feature, low-to-moderate malignancy probability (sub-classify 4A/4B per the overall image)
| Internal echogenicity | Anechoic (simple-cyst-like) |
|---|---|
| Shape | Oval |
| Orientation | Parallel (aspect ratio < 1) |
| Margin | Circumscribed |
| Posterior features | No change |
| Calcifications | None |
| Associated features | None |
→Suggested categoryBI-RADS 2 (benign)
- Read：Meets simple-cyst criteria (anechoic, circumscribed, posterior enhancement/no change, no suspicious features)
- Management：BI-RADS 2 benign: routine screening, no biopsy or short-interval follow-up
- Note：BI-RADS has no official point algorithm; the category is set by the most suspicious feature, and the final category needs the physician's integrated judgement
Common questions
What is Breast Ultrasound BI-RADS Structured Read?
Enter 5th-edition breast-ultrasound lexicon features and get a suggested BI-RADS category by 'most suspicious feature decides the category'. Instant, browser-side.
How is Breast Ultrasound BI-RADS Structured Read calculated? What is the core formula?
Simple-cyst pattern → 2; all benign-leaning features → 3; any suspicious feature (irregular shape, not parallel, non-circumscribed margin, complex, posterior shadowing, suspicious calcifications, associated features) → 4–5 by number/severity.
When is Breast Ultrasound BI-RADS Structured Read used?
Structured assistance in assigning a breast-ultrasound BI-RADS category from descriptors.
What are the key clinical points for Breast Ultrasound BI-RADS Structured Read?
BI-RADS has no official point algorithm — the category is set by the most suspicious feature. Spiculation or skin/nipple retraction lean toward category 5. A simple-cyst pattern (anechoic, circumscribed, posterior enhancement) is category 2. The 4A/4B/4C sub-division is the physician's integrated malignancy estimate.
What are the limits and cautions when using Breast Ultrasound 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 Breast Ultrasound 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.
