Posttreatment Follow-Up MR Imaging Biomarkers of Collateral Status Are Associated with Short-Term Outcomes in Large-Vessel Acute Ischemic Stroke

Key Points

• This research aims to evaluate the association between posttreatment MRI biomarkers and short-term outcomes in large-vessel acute ischemic stroke.
• Utilized follow-up MRI imaging to assess biomarker levels after treatment
• Analyzed persistent perfusion deficits and collateral dynamics
• Evaluated neurologic outcomes in large-vessel stroke patients
• NFS on MRI reliably indicates persistent perfusion deficits and correlates with early neurologic outcomes
• SBS showed some relationship to collateral dynamics but did not provide significant independent prognostic information
