We investigated white matter remodeling after stroke using Gaussian diffusion tensor imaging (DTI), q-ball, persistent angle structure (PAS) MRI and gold standard immuno-histochemistry staining. We demonstrate that MRI fractional anisotropy (FA) identifies tissue with white matter reorganization, fiber orientation of axonal projections from Gaussian DTI, orientation distribution function (ODF) in q-ball, and PAS MRI detects changes of axonal orientation in the ischemic boundary region after stroke. PAS and ODF in q-ball provide the correct fiber crossing information in the layer between corpus callosum and cortex.
