Abstract: Diffusion tensor imaging (DTI) can be used to characterize the orientation of water diffusion, and track white matter fiber bundles. The decrease of fractional anisotropy after stroke indicates impairment of structural integrity of fibers, even Wallerian degeneration if serious; in another hand, the increase of fractional anisotropy relates to the more recovery of motor function. The affected/unaffected ratios of fractional anisotropy are more suitable for predicting motor function recovery after stroke. The changes of corticospinal tract in diffusion tensor tractography can also predict the motor outcome in stroke patients.

Key words: stroke, diffusion tensor imaging, motor function, prognosis, review
