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

Abstract

NFS on posttreatment MRI is a robust imaging biomarker of persistent perfusion deficits and early neurologic outcome, even after successful reperfusion. SBS may reflect complementary collateral dynamics but showed limited independent prognostic utility.
