Figure 5. Color-coded fractional anisotropy (FA) values on arcuate fasciculus in 40 GW and 3 years old subjects.

Figure 5.

Note that regions with FA values lower than 0.15–0.2 are observed in the majority (40 GW) and peripheral regions (3 years old) of the arcuate fasciculus that cannot be detected with popular DTI analysis methods with an FA threshold (Modified from Wilkinson et al., 2017, with permission). In addition to other technical issues including the quality of MRI scan acquisition and analysis, thresholding parameters based on FA values are important factors when performing tractography.
