Diameters, distances, lengths (unit: millimeter) and angles (unit: degree) were analyzed for differences between preterm (n = 24) and fullterm infants (n = 20) using ANCOVA. Results are given as mean ± standard deviation. p-Values are considered significant when printed in bold. CC = corpus callosum; AC = anterior commissure; PC = posterior commissure, ICC = intra-cranial cavity.
