The protocols were applied to a DTI database of adult normal subjects to study size, fractional anisotropy (FA), and T 2 of individual white matter tracts.  ...  Tractography based on diffusion tensor imaging (DTI) allows visualization of white matter tracts. In this study, protocols to reconstruct eleven major white matter tracts are described.  ...  It can quantitatively illustrate trajectories of various white matter tracts, which is useful not only for educational purposes, but also for advancing our understanding of abnormal brain anatomy.  ...
