[Abstract] Objective: To classify the acute stroke lesions according to the diffusion kurtosis imaging (DKI) parameters and discuss the significance of the classification in diagnosis and prognosis.Materials and Methods: We chose 46 acute stroke lesions in brain and divided into 4 types. MK, Ka and Kr show hyper-intensity in Type Ⅰ. MK, Ka and Kr show isointensity or hypo-intensity in Type Ⅱ. MK, Ka and Kr show mixed signal intensity in Type Ⅲ. The ranges or intensity of MK, Ka and Kr are diverse in Type IV. The difference of DKI parameters between four types was accessed by one-way analysis of variance. We chose one case of each type to analyze the prognosis.Results: It shows that MK%, Ka% and Kr% of four types have a significant difference. Other parameters have no significant difference. Type Ⅰ may indicate the bad prognosis. Type Ⅱ and Type Ⅲ may indicate better prognosis, the volume of lesions may decrease.Conclusions: To some degree, the classification of acute stroke lesion by DKI parameters has significance in diagnosis, treatment and prognosis.
