The purpose of this exhibit is to present the basics of diffusion kurtosis imaging (DKI), normal DKI atlas of the brain, and to discuss clinical usefulness. DKI is recently developed technique that characterizes non-Gaussian water diffusion, which are different from conventional diffusional metrics, such as fractional anisotropy (FA). In some clinical situations, DKI has showed better results, compared with conventional FA or apparent diffusion coefficient investigation. This technique has potential to provide new and additional information to conventional diffusional metrics in routine clinical study.
