Due to the parabolic form of the argument in the signal model for diffusional kurtosis imaging, a limit must be placed on the maximum b-value sampled for the fitting function to monotonically decrease with increased diffusion weighting. Here, we present a new way to interpret and estimate kurtosis as anomalous subdiffusion, without restrictions on the maximum b-value.
