摘要
目的探究超声联合磁共振(MRI)对胎儿中枢神经系统畸形的诊断价值。方法选取2008年至2018年我院妇产科诊治的产前检查疑似胎儿中枢神经系统畸形孕妇80例进行研究,所有患儿均在分娩或引产后被证实。孕妇均分别行超声和磁共振检查,观察两种检查方法诊断结果、图像质量、灵敏度和特异度。结果共检出中枢神经系统畸形80例,超声与磁共振检查结果相符有37.5%,结果增加额外信息58.8%,磁共振更正超声检查结果3.8%。磁共振图像质量评分明显高于超声,差异具有统计学意义(P<0.05)。超声灵敏度64.7%、特异度62.9%、阳性预测值45.8%、阴性预测值78.6%,准确率68.0%;磁共振灵敏度92.3%、特异度84.6%、阳性预测值75.0%、阴性预测值95.7%,准确率81.3%。结论超声联合磁共振对胎儿中枢神经系统畸形诊断价值较高,两种方法灵敏度、特异度相似,但磁共振费用较高,超声费用较低,因此可以将超声作为主要检查,磁共振作为补充检查,以提高检出率。
Objective To investigate the diagnostic value of ultrasound combined with magnetic resonance imaging(MRI)in fetal central nervous system malformation.Methods A total of 80 pregnant women with suspected fetal central nervous system malformation by gestational examination in our obstetrics and gynecology department in 2008-2018 were enrolled.All children were confirmed after childbirth or induction of labor.Ultrasound and magnetic resonance imaging were performed in pregnant women,and the diagnostic results,image quality,sensitivity,and specificity of the two examination methods were observed.Results A total of 80 cases of central nervous system malformation were detected.The 37.5%results of ultrasound and magnetic resonance examination were consistent,the 58.8%results increased additional information,and the magnetic resonance imaging corrected 3.8%of results.The magnetic resonance image quality score was significantly higher than that of ultrasound(P<0.05).Ultrasound sensitivity was 64.7%,specificity 62.9%,positive predictive value 45.8%,negative predictive value 78.6%,accuracy 68.0%;magnetic resonance sensitivity was 92.3%,specificity 84.6%,positive predictive value 75.0%,negative predictive value 95.7%,accuracy 81.3%.Conclusion Ultrasound combined with magnetic resonance imaging has a high diagnostic value for fetal central nervous system malformation.The sensitivity and specificity of the two methods are similar,but the magnetic resonance imaging cost is high,and the ultrasonic cost is low.Therefore,ultrasound can be used as the main examination and magnetic resonance as a supplementary examination,improving the detection rate.
