摘　　要：目的探讨3.0T磁共振(MRI)与超声在诊断胼胝体发育不全(ACC)胎儿中的应用。方法选取医院2015年5月~2018年5月在产前检查中发现可疑ACC的60例孕妇参加此次研究,对其临床资料进行回顾性分析,所有孕妇均进行3.0T MRI与超声检查。记录3.0TMRI与超声检查诊断ACC的分型情况,并对比3.0T MRI与超声诊断的敏感度、特异度、准确性及Kappa值。结果 3.0T MRI检查完全型ACC及部分型ACC的正确率均明显高于超声检查(P<0.05),检查结果与分娩后临床诊断结果的一致性明显高于超声检查(P<0.05)。结论 3.0T MRI与超声检查相比,对诊断ACC的敏感度、特异度及准确性较高,分型也较准确,具有较高的诊断价值。Objective To explore the application of 3.0 T magnetic resonance imaging(MRI) and ultrasound in the diagnosis of agenesis of corpus callosum(ACC) in fetuses. Methods 60 cases of pregnant women with suspected ACC found in the prenatal examination from May 2015 to May 2018 were enrolled in the study. The clinical data were retrospectively analyzed. All pregnant women were given 3.0 T MRI and ultrasound. The classification of ACC was diagnosed by 3.0 T MRI and ultrasound and the sensitivity, specificity, accuracy and Kappa value of 3.0 T MRI and ultrasound diagnosis were compared. Results The correct rates of complete ACC and partial ACC by 3.0 T MRI were significantly higher than thoseby ultrasound(P<0.05), and the consistency between examination results and clinical diagnosis results after delivery was significantly higher than that of ultrasound(P<0.05). Conclusion Compared with ultrasound, 3.0 T MRI has higher sensitivity, specificity and accuracy in the diagnosis of ACC, and it has more accurate classification, and has higher diagnostic value.
