The brain development of cyto- and myeloarchitecture undergoes rapid and intensive changes during the third trimester. Diffusion tensor imaging (DTI) probes the microstructural organization of brain tissue by measuring the three-dimensional spatial diffusion of water molecules1. Using mean diffusivity (MD) and fractional anisotropy (FA), we show the spatiotemporal pattern of cortical and superficial white matter maturation in preterm neonates. This result might be useful in the prediction of neurodevelopmental outcome and functional impairments in preterm survivors.
