Infant born preterm have a high incidence of neurodevelopmental impairment, comparing with full-term infants. Development of brain white matter (WM) study based on DTI may allow prediction of later neurodevlopmental outcome. we performed analyses of brain development between full-term infants and preterm infants at equivalent age using TBSS. Group-wise voxel-based comparisons between full-term infants and preterm infants revealed significantly decreased FA values in preterm infants at term equivalent age. We show that growth of white matter is gestation dependent. Longitudinal study is needed to define the catch-up growth in preterm infants.
