Diffusion
measurements were performed 2, 9 and 90 days after stroke onset, estimating
the mean diffusivity (MD), the apparent diffusion kurtosis (ADK) and the
fractional anisotropy (FA). Tissue outcome at day 90 was dependent on tissue
type, i.e. white- or grey matter, as well as location. For instance, deep
white matter developed gliosis, while subcortical U-fibres pseudonormalized.
FA and ADK obtained at day 2 predicted the tissue outcome at day 90 in white
matter.
