Identification of Neonatal White Matter on DTI: Influence of More Inclusive Thresholds for Atlas Segmentation
Figure 5
Regional WM mean DTI values measured using different FA thresholds.
Mean (±95%CI) values of fractional anisotropy (a), axial diffusivity (b), and radial diffusivity (c), within WM regions originally selected with the neonatal atlas and trace <0.006 threshold, and with FA>0.15, FA>0.20, and FA>0.25 thresholds in left and right hemispheres represented by adjacent left and right bars.
