The
apparent diffusional kurtosis for the Krger model is calculated as a function
of the gradient pulse duration. It is found that the error relative to the
true value is at most a few percent for the parameter range of interest for
brain. This result helps to justify the use of larger gradient pulse
durations for diffusion-weighted imaging estimation of the diffusional
kurtosis.
