In this report we compare in vivo diffusion kurtosis measurements acquired with short and long echo times (TE) and discuss their potential for deriving a diffusional kurtosis measures for myelin water in vivo. Our findings provide initial evidence that the apparent kurtosis coefficient vary significantly with TE indicating differences between diffusional characteristics of T2 water pools in white matter.
