ACR BI-RADS 5th Edition Mammography Report Interpreter

Clinical Context & Background

Choose the category already assigned by a radiologist to interpret the ACR BI-RADS Atlas, 5th Edition (2013), mammography source table. Version, modality, origin, workup state, and biopsy coherence follow directly from that supported category and are presented as guidance instead of repeated form entries. This page does not analyze images, derive or override a category, reverse-classify a probability, or issue a management recommendation.
ACR released BI-RADS v2025 in December 2025. This validated historical implementation does not accept v2025, ultrasound, MRI, contrast-enhanced mammography, self-assigned, or AI-assigned categories pending a separate public-table validation.
Formula Logic
Exact identity lookup of a coherent radiologist-assigned 5th Edition mammography category: 0, 1, 2, 3, 4, 4a, 4b, 4c, 5, or 6. No numeric aliases or rounding.

When To Use

  • Use ACR BI-RADS 5th Edition Mammography Report Interpreter when strictly interprets a radiologist-assigned ACR BI-RADS 5th Edition (2013) mammography assessment category and its source-table likelihood interval.
  • Confirm that the patient, diagnosis, disease phase, and available inputs match the cited model before calculation.

How To Interpret

  • Interpret the displayed result using the calculator-specific formula and reference table, spanning 0 through 6.
  • A boundary result should prompt input verification and clinical review rather than false precision.

What To Do Next

  • Integrate the result with invasive versus in-situ status, stage, receptor biology, treatment timing, genomic testing, comorbidity, and patient goals.
  • Document the inputs, result, timing, and clinical context so the assessment can be reproduced.

Limitations

  • Do not interchange screening-risk, DCIS, invasive prognosis, genomic, and post-neoadjuvant tools.
  • The result supports clinician judgment and does not independently determine treatment.

How to apply this result

For a representative case, verify Radiologist-Assigned BI-RADS Category, calculate the result, and confirm that its classification matches the highlighted reference band before continuing the disease-specific pathway.

Calculation verification history

Verified

  1. : Production browser revalidation

    • Three source-backed BI-RADS cases passed through visible production controls at Categories 0, 4B, and 6.
    • No unexpected N/A, literal undefined value, stale control, unsupported risk gauge, or browser-console error was observed.
    Download latest production check (Excel)

    Case-level evidence is retained in validation/browser-revalidation/birads-breast-imaging-reporting-system-2026-08-03.json.

  2. : Production browser validation

    • Ten source-backed cases were exercised on the public production route through visible browser controls; 10/10 case records passed their expected-versus-observed assertions across 11 visible submissions.
    • Overall browser status: failed-console. medium: Production emitted minified React error #418 during route loads and interactions.
    • Case-level inputs, expected and observed results, reset/repeat behavior, failure reproductions, and console evidence are retained in the production-browser evidence record.

    Case-level production evidence is retained in validation/browser-production/birads-breast-imaging-reporting-system.json.

  3. : Input workflow simplified and revalidated

    • Reduced the public form to result-, branch-, unit-, and applicability-changing inputs; removed or consolidated non-scoring, administrative, and duplicate questions.
    • Preserved the verified calculation or report-interpretation logic, thresholds, model version, component logic, and supported result pathways behind strict deterministic adapters.
    • Passed the calculator-specific regression audit, adapter-parity and malformed-input checks, the 144-calculator input-quality audit, and the 43-calculator entry-burden audit.

  4. : Full validation test

    • 400/400 independently expected identity, category, interval-text, malformed-input, applicability, wording, trace, UI, immutability, registry, inventory, report, history, and mirror assertions passed with zero category mismatch.
    • This is source-to-code implementation verification, not independent clinical validation, image interpretation, individualized probability estimation, or management advice.

  5. : Correction

    • Locked the permanent route to ACR BI-RADS 5th Edition (2013) mammography reported-assessment interpretation and explicitly excluded v2025 and other modalities pending separate validation.
    • Replaced numeric and float aliases with literal category strings, restored generic Category 4 and exact 4A/4B/4C endpoint wording, and corrected Category 6 to N/A rather than 100%.
    • Removed the Category 1 default, coercion, crash fallthrough, image-feature assignment claims, and app-directed management; added exact provenance, workflow, biopsy, trace, reset, snapshot, and immutability gates.

    Included in the current validation report.

Verification confirms the calculator implementation against the cited model; it is not independent clinical validation, regulatory approval, or medical advice.
