摘　　要：目的探讨磁共振成像(MRI)在胎儿产前检查中的临床应用价值。方法回顾性分析我院2020年11月至2021年12月间经院内外超声产前筛查发现异常而行针对性胎儿MRI检查252例胎儿的影像及相关资料。结果中枢神经系统(脑部)MRI检查206例,主要以胎儿脑部发育及畸形为主;腹盆部MRI检查31例,主要以泌尿及生殖系异常为主,部分为腹部肿瘤性病变;胸部MRI检查7例,主要以肺部先天畸形为主;脊柱MRI检查6例,颌面部及颈部MRI检查各1例。结论在胎儿产前影像学检查中,针对性胎儿MRI检查属Ⅳ级产前影像诊断,可以确认超声检查结果或提供比超声更多的诊断信息,对于明确产前诊断、促进优生优育有重要价值。Objective To explore the clinical value of magnetic resonance imaging(MRI)in prenatal diagnosis for fetus.Methods Two hundred and fifty-two fetuses with abnormal prenatal ultrasound screening results,admitted in our hospital from November 2020 to December 2020,were enrolled in this study.Fetal MRI were performed on all fetuses.And all the clinical data and radiological images were analyzed retrospectively.Results Fetal brain MRI was performed in 206 cases,and dysplasia and malformation were the most common abnormalities.31 cases underwent MRI of abdomen and pelvis,the main abnormalitiesmostly occurred tourogenital system,and abdominal tumors were also observed.Chest MRI was performed in 7 cases,congenital malformation of lungs were the most common abnormalities,MRI examination of the spine was performed in 6 cases,maxillofacial and neck in 1 cases respectively.Conclusion Fetal MRI belongs to the gradeⅣprenatal radiological examinations,which can provide more effective information when compared with ultrasound,and shows great value in prenatal diagnosis and promotes aristogenesis and stirpiculture.
