| Abstract: | Diffusion kurtosis imaging (DKI) is an emerging diffusion index to quantify non-Gaussian diffusion process in vivo, particularly important for characterizing microstructure of biological tissue. As an extension of conventional diffusion MRI, DKI has been postulated useful in classifying heterogeneous brain injury of acute ischemic stroke. In this article, recent progresses on theoretical and experimental aspects of DKI in ischemic stroke imaging were discussed. |
