↵a One hundred sixty-six neonates returned for neurodevelopmental follow-up. DTI data were acquired in 75 of the neonates early and in 75 of the neonates at early and late time points (150 scans). Sixteen neonates had late scans for a total of 241 scans.
↵b Age corrected for prematurity.
↵c The mean composite score in a normative population is 100 ± 15.
