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.
| Most severe luminal stenosis (per-patient) | 0% (no plaque/stenosis) |
|---|---|
| Ischaemia modifier (CT-FFR/CTP) | Not done |
| High-risk plaque (HRP) | Yes |
→CategoryCAD-RADS 0 / HRP
- Category：CAD-RADS 0: 0% (no plaque/stenosis)
- Management：No obstructive CAD: no further cardiac testing; general prevention by risk factors
- Modifiers：HRP (included); also annotate P1–P4 plaque burden, S stent, G graft, E non-atherosclerotic as needed
| Most severe luminal stenosis (per-patient) | Non-diagnostic (≥ 50% of segments uninterpretable) |
|---|---|
| Ischaemia modifier (CT-FFR/CTP) | I± borderline/indeterminate |
| High-risk plaque (HRP) | No |
→CategoryCAD-RADS N / I±
- Category：CAD-RADS N: Non-diagnostic (≥ 50% of segments uninterpretable)
- Management：Non-diagnostic study: further testing (repeat CCTA/functional/ICA), clinically determined
- Modifiers：I± (included); also annotate P1–P4 plaque burden, S stent, G graft, E non-atherosclerotic as needed
Common questions
What is Coronary CTA CAD-RADS 2.0 Classification?
Grade coronary CTA by the most severe stenosis (0–5/N) with ischaemia and high-risk-plaque modifiers per CAD-RADS 2.0, with management direction. Instant, browser-side.
How is Coronary CTA CAD-RADS 2.0 Classification calculated? What is the core formula?
0 none, 1–2 non-obstructive, 3 moderate (50–69%), 4A severe (70–99%), 4B left main > 50% or 3-vessel ≥ 70%, 5 occlusion, N non-diagnostic. Modifiers: P (plaque burden), HRP, I (ischaemia), S/G/E.
When is Coronary CTA CAD-RADS 2.0 Classification used?
Standardise coronary CTA reporting and the downstream management direction.
What are the key clinical points for Coronary CTA CAD-RADS 2.0 Classification?
Graded by the per-patient most severe luminal stenosis (segments > 1.5 mm). CAD-RADS 3 → consider functional assessment (CT-FFR/CTP/stress) plus GDMT. CAD-RADS 4B (high-risk anatomy) → ICA recommended. High-risk plaque or positive ischaemia (I+) favours ICA for revascularisation.
What are the limits and cautions when using Coronary CTA CAD-RADS 2.0 Classification?
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.
How is Coronary CTA CAD-RADS 2.0 Classification calculated in practice? Can you show a worked example?
