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.  ...

At the beginning some questions may arise: Is learning anatomy necessary? What will we learn? We already know. Most of the learned subjects in anatomy are unnecessary and are not used.  ...  There has been always a connection between research interest and clinical practice. How can we learn it? Is through clinical application? Is this way ethical? It is questionable.  ...  As a result, to reach the better goals on anatomy education, it can be better for anatomy practical education that matter the opinion of students.  ...
