Role of Recanalization in Acute Stroke Outcome: Rationale for a CT Angiogram-Based “Benefit of Recanalization” Model: Fig 1.

Abstract
BACKGROUND AND PURPOSE: In acute middle cerebral artery (MCA) stroke, CT angiographic (CTA) source images (CTA-SI) identify tissue likely to infarct despite early recanalization. This pilot study evaluated the impact of recanalization status on clinical and radiologic predictors of patient outcomes.
