Ischemic stroke (IS) leads to local metabolic and
functional impairment in the vicinity of the lesion.
However, the global effect of IS remains to be
clarified.In this study we presented the global effect
of IS by estimating the cerebral oxygen extraction
fraction (OEF) based on the magnetic resonance
susceptibility weighted imaging.This preliminary study
may provide a meaningful reference for future researches
towards a better understanding of the disease dynamic of
