Early Post-Thrombectomy MRI Markers

This observational study systematically characterized MRI markers at serial follow-up early after EVT. The heterogeneous and dynamic evolution observed during the hours and days after EVT in most patients suggests further opportunity to intervene, with early incomplete reperfusion and reperfusion injury as prognostic differentiators. Our findings can serve as a roadmap for designing future clinical trials to develop adjunctive therapies targeting these imaging markers.
