Comparison of Diffusion Tensor Imaging Metrics in Normal-Appearing White Matter to Cerebrovascular Lesions and Correlation with Cerebrovascular Disease Risk Factors and Severity

Figure 7

FA in NAWM in CVD subjects with various mRS scores (0, 1, and 2) (a) and FA in NAWM weighted by the normalized WMH volumes in CVD subjects with different mRS scores (0, 1, and 2) (b). The bars and error bars in panel (a) represent the mean and standard deviation of FA in NAWM. The bars and error bars in panel (b) represent the weighted mean and weighted standard deviation of FA in NAWM following statistical weighting by the normalized WMH volumes. Data with asterisk and double asterisk were significantly different as detected by pairwise comparison following the ANCOVA test with value < 0.002 and value < 0.001, respectively.
