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

Figure 6

FA in NAWM in CVD subjects without and with hypertension (HTN) (a) and FA in NAWM weighted by the normalized WMH volumes in CVD subjects without and with HTN (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 were significantly different as detected by ANCOVA test ( value < 0.001).
