AbstractThis study aimed to investigate the changes of term and preterm neonates with post-menstrual ages (PMA). 44 healthy neonates with PMA ranging from 33 to 42 weeks were enrolled. Diffusion tensor images were acquired and analyzed by tract-based spatial statistics (TBSS). 8 regions of centrum semiovale (CS), corpus callosum (CC), internal capsule (IC), external capsule (EC), optic radiation (OR), and anterior limb of internal capsule (ALIC) were selected. FA values generally increased while AD, RD, and MD values decreased significantly in most regions in term group. ALIC exhibited the lowest diffusion values. Moreover, the slope rates of SCC, CS, OR, EC with PMA were significant higher than those of other regions, indicating their rapid maturation.
