In acute ischemic stroke with unknown time of onset, magnetic resonance (MR)‐based diffusion‐weighted imaging (DWI) and fluid‐attenuated inversion recovery (FLAIR) estimates lesion age to guide intravenous thrombolysis. Computed tomography (CT)‐based quantitative net water uptake (NWU) may be a potential alternative. The purpose of this study was to directly compare CT‐based NWU to magnetic resonance imaging (MRI) at identifying patients with lesion age < 4.5 hours from symptom onset.
