The current study demonstrated the utility of bi- and
stretched-exponential diffusion models in characterize
the non-Gaussian diffusion behavior in acute/subacute
stroke. The preliminary results suggest that the bi- and
stretched -exponential model can help better describe
the complex behavior of water diffusion in
acute/subacute stroke, and may provide more detailed and
useful metrics for lesion assessment and prognosis.
