Biexponential diffusion tensor analysis in the extended range of diffusion-encoding gradients permits one to overcome the limitations of conventional DTI based on the assumption of the Gaussian model with regard of displacements of water molecules in tissue. We illustrate the benefits of this approach with an in vivo diffusion study of the human brain performed on 14 healthy volunteers. Novel parameter maps are discussed in the context of their potential applications in brain diagnostics.
