Abstract: One aspect of the present disclosure relates to a system that can perform double pulsed diffusional kurtosis imaging (DP-DKI). Image data can be received. The image data can be acquired using a double pulsed field gradient (d-PFG) diffusion sequence. A six dimensional (6D) diffusional kurtosis for the image data can be determined. A magnitude of the image data can be determined in terms of the 6D diffusional kurtosis. DP-DKI can isolate the contributions to the d-PFG diffusion sequence, which can represent leading diffusion effects, that cannot be seen from single pulsed field gradient (s-PFG) diffusion sequences.
