This study aims to investigate the feasibility of simultaneously measuring perfusion and diffusion in the acute phase of ischemic stroke with the combined IntraVoxel Incoherent Motion and non-gaussian Diffusional Kurtosis Imaging (DKI-IVIM). For the fifteen patients enrolled, a significant decrease for the diffusion coefficient D and a significant increase in the kurtosis coefficient was observed in the infarcted lesions. Regarding the perfusion, the perfusion fraction f significantly decreased. Enhanced tissues heterogeneity was observable on reconstructed K maps. DKI-IVIM can provide with a clinically acceptable acquisition time both diffusion and perfusion characterization that might be of great interest for stroke diagnosis.
