Study of white matter anatomy and 3D tract reconstruction by diffusion tensor imaging

Abstract “Diffusion Tensor Imaging” (DTI) has the unique capability to represent the macroscopic white matter architecture. Based on DTI, tractography is able to render 3D trajectories of tracts. There are no other technique that can produce equivalent anatomical information, and, thus, tractography is a powerful method to investigate human brain anatomy. Here, we present an overview of the principles, advantages, shortcomings and possibilities of these methods. © 2010 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 20, 51–56, 2010
