Diffusion Tensor Imaging and Fractional Anisotropy

Abstract

The previous chapter briefly described the physics behind diffusion anisotropy and diffusion-tensor imaging. The current chapter throws light on the most important scalar derivative of DTI, i.e. fractional anisotropy and its clinical utility on the brain white matter. The evidence on factors affecting FA values and normative FA have been outlined in-depth as well.
