DTI, qMTI, and multicomponent T

relaxometry
might help quantify changes related to demyelination. To
understand the interplay different MRI methods have as
white matter changes in the corpus callosum of the
cuprizone mouse model,
in
vivo
T

-weighted
(T2w) and MTI were acquired weekly in control and
cuprizone-fed mice. Weekly DTI, qMTI, T

/T
2
relaxometry,
T2w imaging, and EM were used to analyze
ex
vivo
tissue
after each week of cuprizone delivery. The addition of
the weekly
ex
vivo
tissue
analysis allows for a more complete understanding of the
correlations between MR metrics and EM measures of
tissue pathology.
