Diffusion-Weighted Imaging-Fluid-Attenuated Inversion Recovery Mismatch Is Associated with 90-Day Functional Outcomes in Patients Undergoing Mechanical Thrombectomy

<b><i>Background and Purpose:</i></b> Diffusion-weighted imaging-fluid-attenuated inversion recovery (DWI-FLAIR) mismatch is an early sign of acute ischemic stroke. DWI-FLAIR mismatch was reported to be valuable to select patients with unknown onset stroke who are eligible to receive intravenous thrombolysis (IVT), but its utility is less studied in patients undergoing mechanical thrombectomy (MT) for acute large vessel...
