Methodology · worked example, guidelines & full notes
Graded by the per-patient most severe luminal stenosis (segments > 1.5 mm).
When to use
Standardise coronary CTA reporting and the downstream management direction.
How it works
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.
Key points
- Graded by the per-patient most severe luminal stenosis (segments > 1.5 mm).
- CAD-RADS 3.
- CAD-RADS 4B (high-risk anatomy)

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) | 50–69% moderate |
|---|---|
| Ischaemia modifier (CT-FFR/CTP) | I+ positive |
| High-risk plaque (HRP) | Yes |
→CategoryCAD-RADS 3 / HRP/I+
- Category：CAD-RADS 3: 50–69% moderate
- Management：optimise medical therapy (GDMT)[Pending update] Some thresholds, grades and management recommendations on this page that conflict with current guidelines or are unverified are temporarily hidden pending verification against the guideline text.
- Modifiers：HRP, I+ (included); also annotate P1–P4 plaque burden, S stent, G graft, E non-atherosclerotic as needed
| 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

FAQ
Frequently asked questions
- 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.
- Does Coronary CTA CAD-RADS 2.0 Classification 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 Coronary CTA CAD-RADS 2.0 Classification calculated in practice? Can you show a worked example?
