Tract-based spatial statistics analysis of the correlation between gestational age at birth and DTI parameters (FA, MD, AD, and RD) in term infants. Background images are FA maps; major white matter tracts are green; voxels in the tract with significant positive correlations (P < .05, corrected) are red; voxels with significant negative correlations (P < .05, corrected) are blue. Widespread positive correlations between FA and gestational age at birth and negative correlations between MD, AD, and RD and gestational age at birth were observed.
