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.
