While CTA measurements of stenosis can sometimes overestimate severity compared to NASCET criteria, advanced analyses such as radiomics, plaque density (Hounsfield units), and soft plaque thickness provide crucial insights into plaque vulnerability and risk of ischemic events. These advanced CT-derived features are predictive of future major adverse cardiovascular events, transient ischemic attack risk, and symptomatic disease, even in cases of mild or no…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
