Clinical workstation organizing radiology images within a tiered classification framework

CAD-RADS 2.0 standardizes coronary CT angiography conclusions by combining the most severe coronary stenosis category, overall plaque burden, and clinically relevant modifiers. The final label summarizes the examination; it does not replace segment-by-segment findings or clinical management judgment.

Category	Most severe finding
CAD-RADS 0	No plaque or stenosis
CAD-RADS 1	1–24% stenosis or plaque without stenosis
CAD-RADS 2	25–49% mild stenosis
CAD-RADS 3	50–69% moderate stenosis
CAD-RADS 4A	70–99% stenosis in one or two vessels
CAD-RADS 4B	Left main at least 50% or three-vessel obstructive disease
CAD-RADS 5	Total coronary occlusion
CAD-RADS N	Nondiagnostic study or segment that prevents reliable categorization
