p Values are for the Wilcoxon–Mann–Whitney test comparing groups with/without reperfusion/recanalisation.
CBF, cerebral blood flow; CBV, cerebral blood volume; CTA, CT angiography; MR, magnetic resonance; MRA, MR angiography; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale.
