Region of interest analysis of FA maps from three longitudinal DTI scans. Region of interest (ROI) analysis of visit 1 and visit 3 were without gradient direction (GD) elimination by quality control (QC) since no corruption was evident. During visit 2, 9 GD (compare Figure 1) had to be eliminated. ROI based mean FA values changed with and without QC, respectively. Although ROI localization was identical for the three visits the respective slices look apparently different due to different slice orientation during acquisition.
