胎儿脑发育的磁共振成像研究进展OA

Fetal magnetic resonance imaging(MRI)is an advanced prenatal imaging diagnostic technology.Beyond the scope of traditional anatomical examinations,it enables non-invasive assessment of in utero metabolic and functional development of the fetal brain and other organs.With the rapid advancement of magnetic resonance technology,fetal functional MRI is expected to become a powerful method for understanding fetal development and early identification of neurological abnormalities and other fetal diseases.At present,the research on fetal magnetic resonance imaging in China mainly focuses on the assessment of normal fetal nervous system development and the study of brain structure in malformed fetuses.However,there is a lack of research on the trajectory of fetal brain functional development,prediction of birth outcomes,and neurobehavioral abilities.This article mainly discusses the progress in magnetic resonance research on fetal brain venous development,metabolism,microstructure,and functional connectivity,and points out the future research directions.This review will provide new methods for evaluating the normal brain development pattern of the fetus and early detection of fetal brain development abnormalities.By observing changes in brain function and metabolic activity,abnormal metabolism and neural signals can be identified,providing a basis for early diagnosis and postnatal treatment of diseases.
