Diffusion kurtosis imaging (DKI) is a recent imaging method that probes the diffusion of water molecules. Whereas diffusion tensor imaging (DTI) models the diffusion as a 3D Gaussian function, DKI takes it one step further by additionally quantifying the degree of non-Gaussian diffusion. DKI diffusion parameters have been shown to yield clinically relevant information that is not captured by a more conventional DTI model. Thanks to the increase of clinical applications, DKI is becoming increasingly popular in neuroimaging. In this chapter, we will review the basics of DKI. Furthermore, we explain how DKI parameters can be estimated with the highest precision and accuracy. Finally, we discuss some applications of DKI.
