Abstract: Diffusion tensor imaging (DTI) could not only reconstruct of the brain white matter neural connectivity, but also show clearly the brain white matter fiber morphology of lesions, either directly or indirectly, which imaged on white matter fiber tracts in the three-dimensional geometric structure by special software for image on the anisotropic thermal motion of water molecules. This paper reviewed the researches on DTI in the assessment of white matter fiber tracts injury and prognosis in patients with stroke.

Key words: diffusion tensor imaging, stroke, white matter fiber tracts, injury, clinical prognosis, review
