Fetal neurosonography detects differences in cortical development and corpus callosum in late‐onset small fetuses

OBJECTIVE To explore whether neurosonography can detect differences in cortical development and corpus callosal length in late-onset small fetuses subclassified into small-for-gestational age (SGA) or growth restricted (FGR). METHODS This was a prospective cohort study in singleton pregnancies, including normally grown fetuses (birth weight between the 10th and 90th centiles) and late-onset small fetuses (estimated fetal weight
