摘　　要：目的 探究产前MRI筛查胎儿透明隔间腔发育异常的应用价值。方法 回顾性分析2021年1月~2024年1月于我院进行产前检查465例产妇临床资料,所有样本均进行产前超声检测,超声结果提示60例胎儿透明隔间腔存在异常,进一步进行MRI检测。记录胎儿透明隔间腔发育异常的种类,同时对比两种检测手段的诊断效能。结果 超声检测结果显示透明隔腔偏小16(26.67%),透明隔腔增宽12(20.00%),透明隔腔末显示10(11.67%),透明隔腔未显示并胼胝体发育不全9(15.00%),透明隔腔缺失6(10.00%),透明隔腔回声异常5(8.33%),无叶全前脑2(3.33%)。MRI检测显示透明隔腔偏小18(30.00%),透明隔腔增宽14(23.33%),透明隔腔未显示11(18.33%),透明隔腔未显示并胼胝体发育不全10(16.67%),透明隔腔缺失7(11.67%)。MRI检查敏感度显著高于超声检查,漏诊率显著低于超声检查(P<0.05)。结论 MRI能提高产前胎儿透明隔间腔发育异常的准确率,适合临床应用推广。Objective To explore the application value of prenatal MRI screening on fetal cavum septum pellucidum(CSP) dysplasia.Methods The clinical data of 465 pregnant women who received prenatal examination in the hospital were retrospectively analyzed from January 2021 to January 2024.All samples were examined by prenatal ultrasound.The ultrasound results showed 60 cases of fetal CSP abnormality,and further MRI was performed.The types of fetal CSP dysplasia were recorded,and the diagnostic efficiency of the two detection methods was compared.Results Ultrasound detection showed small CSP in 16 cases(26.67%),widened CSP in 12 cases(20.00%),not displayed CSP in 10 cases(16.67%),not displayed CSP with corpus callosum agenesis in 9 cases(15.00%),CSP loss in 6 cases(10.00%),CSP echo abnormality in 5 cases(8.33%),and aloba r forebrain in 2 cases(3.33%).MRI examination showed that the CSP was small in 18 cases(30.00%),the CSP was widened in 14 cases(23.33%),CSP was not shown in 11 cases(18.33%),CSP was not shown and the corpus callosum was not developed in 10cases(16.67%),and the CSP was missing in 7 cases(11.67%).The sensitivity of MRI was significantly higher than that of ultrasound,and the missed diagnosis rate was significantly lower than that of ultrasound(P<0.05).Conclusion MRI can enhance the accuracy rate of prenatal fetal cavum septum pellucidum dysplasia.
