Research progress in imaging evaluation of the development of fetal corpus callosum
Corpus callosum is an important indicator to assess the normal development of the brain,and it is also a hot spot in the field of prenatal diagnosis at home and abroad.Among the imaging methods used to assess the development of corpus callosum before prenatum,fetal cranial ultrasound has the advantages of ra-pidity,safety,good reproducibility and dynamic observation.Magnetic resonance imaging(MRI)is intuitive,accurate and comprehensive,but it is affected by factors such as fetal movement,and is expensive and not widely used.This article reviewed and analyzed the results of recent studies on the evaluation of fetal corpus callosum development by imaging techniques at home and abroad,aiming to analyze and compare the clinical application value of the two methods in prenatal diagnosis.
