We constructed a 4D spatiotemporal atlas of the normal fetal brain development from 23 to 38 gestational weeks in a Chinese population. We depicted the developmental trajectories of morphological indices of the cerebral cortex, which showed a characteristic regional variations and indicated the developmental order and rates in the different cortical parcels. The fetal brain atlas and fetal cerebral cortex trajectory offer a better understanding of fetal brain development and can be used as an analytic reference for clinicians in diagnostic or research settings.
