Time-Dependent Topography: How Specific ASPECTS Regions Predict Outcomes in Early vs. Extended Window Large Vessel Occlusion Stroke
A post-hoc analysis of 1,040 LVO stroke patients reveals that the prognostic value of specific brain regions varies significantly between early (0-6h) and extended (6-24h) time windows, identifying the insula, caudate, and M6 as early-window markers, and M3 and M5 as late-window predictors.
