Patient flow in the ESCAPE-MeVO trial. D: days; DWI-MRI: diffusion-weighted MRI (magnetic resonance imaging); h: hours; MRA: MR-angiography; mRS: modified Rankin Scale; NCCT: non-contrast CT; NIHSS: National Institutes of Health Stroke Scale; R, randomization. For cases in which an MRI at 18–54 hours cannot be obtained (e.g. due to unavailability of an MR scanner, patient agitation etc.), an NCCT can be performed instead.
