The use of soft prior regularization (SPR) improves the SGM viscoelastic property measures, μ and ξ. (A) Coefficient of variation, CV, for each SGM property measured with and without SPR. Without SPR, the CV for each measure is much larger indicating greater measurement uncertainty. (B) Effect size (Cohen's d) of difference between SGM properties and those of the entire cerebrum (CB) as measured using SPR and without. For all measures, d is greater with SPR, demonstrating the improved measurement sensitivity. [Color figure can be viewed at http://wileyonlinelibrary.com]
