In the recent years, diffusion kurtosis imaging has become an important method for the quantification of the non-Gaussian diffusion in brain tissue by means of magnetic resonance imaging. In this work we carry out an experimental investigation of the optimal allowed range of b-values according to the type of tissue under examination and an applied set of gradient directions. We examine how the mean-diffusivity and mean-kurtosis maps are influenced by the chosen range of b-values and propose an optimization scheme.
