Fig. 3From: Multimodality CT based imaging to determine clot characteristics and recanalization with intravenous tPA in patients with acute ischemic strokeA theoretical explanation of recanalization response to IV tPA and intra-arterial therapy based on collateral status, original composition of clot, and efficiency of angio-architecture. All possible combinations are not included. Adapted from Qazi et al. 2015 [10]Back to article page
