Abstract：Objective To explore the diagnostic value of magnetic resonance imaging(MRI)in fetal malformations of corti-cal development(MCDs).Methods MRI images of 54 cases of fetal MCDs were analyzed retrospectively,and their MRI fea-tures were summarized.Results Among 54 cases of MCDs,there were 10 cases of Microcephaly,5 cases of Hemimegalen-cephaly,and 5 cases of periventricular nodular heterotopia,9 cases of Lissencephaly spectrum,11 cases of Polymicrogyria,8 cases of Schizencephaly,6 cases of Focal cortical dysplasia.MRI findings of 54 cases of MCDs were as follows:there were 45 cases of abnormal development of the sylvian fissure,28 cases of delayed achievement of cortical milestones,33 cases of prema-ture or aberrant appearance of sulcation,44 cases of the irregular ventricular borders,36 cases of abnormal cortical thickness,39 cases of the abnormal shape and orientation of the sulci and gyri,42 cases of the irregular,abnormal,asymmetric and en-larged hemisphere,26 cases of simplified cortex,and 8 cases of non-continuous cortex or cleft in intraparenchymal echogenic nodules.Conclusion In the prenatal diagnostic imaging examinations of MCDs,MRI is superior to ultrasound,which can im-prove the diagnostic rate of MCDs in fetus.
