Diffusion kurtosis imaging (DKI) is an advanced neuroimaging modality which is an extension of diffusion tensor imaging by estimating the kurtosis (skewed distribution) of water diffusion based on a probability distribution function . It provides a high order diffusion of water distribution andand analyses as well asand also quantifies the diffusion restriction. The kurtosis is a general, dimensionless statistic for quantifying non-guassianity - that is, the difference from a normal/random distribution - of any distribution. It also providesmay be used in the biochemical environmentimaging of a neuronal tissue stroke4.
