We studied 92 prematurely born neonates (<31 weeks) at term equivalent age using quantitative Fiber Tracking (FT), generated on 3.0T MRI. Patients were divided into three groups, based on scoring of the conventional MRIs. Using a general linear model, the effects of factor (group) and variables (gestational age, birth weight and head circumference) were tested. For the FA and ADC in corpus callosum fiber bundle, a significant relation with MR group was observed. Furthermore, for the corpus callosum, volume, Cl and length depended significantly on the gestational age, suggesting an influence of age at birth on brain maturation.
