CTA Radiomics of Plaque and Lumen Predicts Stroke Recurrence Better Than Plaque Alone

CTA radiomics of both plaque and lumen predicted 1-year stroke recurrence better than plaque-only features (testing AUC 0.74-0.81 vs 0.58-0.62) in 203 patients with symptomatic intracranial atherosclerotic stenosis.

• No significant difference in clinical variables was found between patients with and without stroke recurrence.
• Models using plaque and lumen features achieved higher discrimination on testing (AUC 0.74-0.81) than plaque-only (AUC 0.58-0.62).
• The study was a substudy of a cohort, with 203 patients randomly split into training (121) and testing (82) sets.
