We explored the remote effect of ischemic stroke by
comparing the microstructural indices and fiber density
in cerebral peduncles (CP) in 14 subjects diagnosed with
single and unilateral ischemic stroke remote to the CP.
Fiber density was dramatically decreased in the CP
ipsilateral to the lesion while mean diffusivity and
fractional anisotropy did not manifest significant
difference between the bilateral CPs. Fiber density may
serve as a sensitive index identifying remote white
matter damage in acute ischemic stroke.
