This study found kurtosis fractional anisotropy values outperformed other DKI-derived parameters in sensitive detection of microstructural white matter damage for early diagnosis of amnestic mild cognitive impairment and Alzheimer's disease.
Figure 1. Comparison results of different DKI-derived parameters between HC and AD, aMCI and AD, and HC and aMCI, respectively. Green represents the FA skeleton overlaid on the FMRIB58_FA template. Yellow indicates the brain structures with significantly decreased parameter values in the aMCI and AD groups (p<0.01, TFCE-corrected). Red indicates the brain structures with significantly increased parameter values in the aMCI and AD groups (p<0.01, TFCE-corrected)
