Abstract

BACKGROUND: Infarct evolution on diffusion-weighted imaging (DWI) after complete recanalization and its relationships to computed tomography perfusion core and outcome remain uncertain. METHODS: From a multicenter registry (2014-2024), we identified 189 patients with anterior-circulation large-vessel occlusion, modified Thrombolysis in Cerebral Infarction grade 3 recanalization, prethrombectomy c…
