🫀 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.
Coronary CTA CAD-RADS 2.0 Classification
Most severe luminal stenosis (per-patient)
Ischaemia modifier (CT-FFR/CTP)
High-risk plaque (HRP)
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 → 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.
