Double‐pulsed diffusional kurtosis imaging
NMR in Biomedicine, 2014Diffusional kurtosis imaging (DKI) is extended to double‐pulsed‐field‐gradient (d‐PFG) diffusion MRI sequences. This gives a practical approach for acquiring and analyzing d‐PFG data. In particular, the leading d‐PFG effects, beyond what conventional single‐pulsed field gradient (s‐PFG) provides, are interpreted in terms of the kurtosis for a diffusion

Diffusion kurtosis imaging (DKI) is a recent imaging method that probes the diffusion of water molecules. Whereas diffusion tensor imaging (DTI) models the diffusion as a 3D Gaussian function, DKI takes it one step further by additionally quantifying the degree of non-Gaussian diffusion.

Is Kurtosis Really "Peakedness?"
The American Statistician, 1970Abstract Kurtosis is best described not as a measure of peakedness versus flatness, as in most texts, but as a measure of unimodality versus bimodality.

Moment kurtosis and graphic 9kurtosis9 statistics do not necessarily measure either 9peakedness9 or peakedness relative to thenormal distribution. Graphic 9kurtosis9 statistics may be largely unrelated to moment kurtosis.

" Given two frequency distributions which have the same variability as measured by the standard deviation, they may be relatively more or less flat-topped than the normal curve. If more flat-topped I term them platy kurtic, if less flat-topped leptokurtic, and if equally flat-topped mesokurtic.
