As significant sensitivity of DKI to tissue pathologies
was recently reported, this imaging modality is widely
suspected to be useful for the neural tissue structure
estimation. Being a Taylor expansion of the diffusion
signal logarithm it deemed to have a validity region. We
assessed the validity of the kurtosis evaluation versus
for a range of b-values versus an analytically
calculated ground truth based on the robust neurite
model, that proved to finely describe the properties of
the tissue. The results of the comparison show extremely
high absolute error even for moderately small b-values
both for extremely high and realistic SNR values.
