胎儿磁共振成像（fetal MRI）具有无电离辐射、软组织分辨率高等优点，可在出生缺陷产前评估中提供精细解剖结构及功能信息；其作为产前诊断高级影像学工具，已整合进产前诊断及胎儿医学的系统化诊疗流程。胎儿MRI的核心价值在于“协助诊断”，为复杂病例提供完善影像学资料，作为启动儿科多学科会诊（MDT）的重要依据，支持制定个体化的围产期管理方案，为出生缺陷的全生命周期管理提供重要支撑。

Fetal magnetic resonance imaging （fetal MRI） offers several distinct advantages，including the absence of ionizing radiation and high soft-tissue contrast resolution，which collectively enable precise anatomical delineation and functional assessment during prenatal evaluation of congenital anomalies. As an advanced prenatal imaging modality，fetal MRI has become an integral component of standardized diagnostic and therapeutic frameworks in prenatal diagnosis and fetal medicine. Its primary clinical value lies in its ability to “assist in diagnosis” decision by providing comprehensive imaging evidence in complex cases，serving as a critical basis for initiating multidisciplinary team （MDT） consultations in pediatrics，and facilitating the formulation of individualized perinatal management strategies. All of these provid significant support for the life-cycle management of birth defects.
