Abstract
In the last 10 years, diffusion in biological tissues is increasingly studied by using magnetic resonance imaging techniques. More recently, diffusion tensor imaging is attracting the biomedical researchers for its application in depiction of fiber tracts based on diffusion anisotropy. For example, information of white matter tracts depicted by diffusion tensor analysis helps neuro-surgical navigation as well as vascular information. In this review paper, determination process of diffusion tensor in multi-channel magnetic resonance data, and several visualization techniques, such as tractography, are described briefly, and then several examples are shown using clinical data. The basic concepts of diffusion tensor analysis, and advantages and disadvantages of the visualization techniques are also discussed.
