Diffusion kurtosis reported to be increase in the lesions of acute cerebral infarction. However, time course of the diffusion kurtosis of the cerebral infarction is not investigated enough. The purpose of the current study is to evaluate the changes in diffusion kurtosis in the cases with early cerebral infarction. Diffusion kurtosis value which is axial to the eigenvector showed increase in the lesions of the early infarction and showed earlier decrease compared to the diffusion weighted images. Additional information for the tissue with very early infarction will be provided by diffusion kurtosis imaging.
