Key Points Question Are clinical outcomes of patients with acute ischemic stroke imaged with initial computed tomography (CT) alone noninferior to those who had additional magnetic resonance imaging (MRI)? Findings In this propensity score–matched cohort study of 246 patients hospitalized with acute ischemic stroke, a diagnostic imaging strategy of initial CT alone was noninferior to initial CT plus additional MRI with regard to clinical outcomes at discharge and at 1 year. Meaning Results of this study suggest that further research is needed to determine which patients hospitalized with acute ischemic stroke benefit from MRI in addition to initial CT.
