- CTA-based Plaque-RADS classification assesses nonstenotic carotid plaques (NSCPs) in embolic stroke of undetermined source (ESUS).
- High-risk NSCPs (Plaque-RADS categories 3-4) are more common on the stroke side and linked to lower prevalence of competing cardioembolic sources.
- Ipsilateral high-risk NSCPs are associated with increased risk of ipsilateral stroke recurrence.
- The study supports the role of high-risk NSCPs as a distinct causal mechanism in ESUS.
- Inter-rater agreement for CTA-based Plaque-RADS classification was excellent (Cohen κ = 0.83).
