Diffusion kurtosis imaging

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 and analyzes and also quantifies the diffusion restriction. The kurtosis is a general, dimensionless statistic for quantifying non-gaussianity – that is, the difference from a normal/random distribution – of any distribution. It may be used in the imaging of stroke4
