摘　　要：目的探讨产前应用超声与MRI联合诊断胎儿畸胎瘤的效能.方法回顾性分析96例接受胎儿畸胎瘤筛查患者资料,比较超声、MRI、超声+MRI诊断胎儿畸胎瘤的准确度、特异度、灵敏度.结果超声诊断骶尾部畸胎瘤与病理结果比较,Kappa值为0.831(95%可信区间0.541~1.121),一致性为88.24%;MRI诊断骶尾部畸胎瘤与病理结果比较,Kappa值为0.914(95%可信区间0.624~1.204),一致性为94.12%;超声+MRI诊断胎儿畸胎瘤灵敏度(96.00%)高于超声(64.00%)、MRI(68.00%)(P<0.05).结论超声、MRI诊断骶尾部畸胎瘤与病理结果一致性良好,两者联合应用于整体胎儿畸胎瘤的产前诊断,可提高诊断的灵敏度.Objective To explore the efficiency of prenatal ultrasound combined with MRI in the diagnosis of fetal teratoma.Methods A total of 96 patients underwent fetal teratoma screening were selected for retrospective analyze to compare the accuracy,specificity and sensitivity of ultrasound,MRI,ultrasound+MRI in the diagnosis of fetal teratoma.Results Compared with the pathological diagnosis of sacrococcygeal teratoma,the Kappa value was 0.831(95%CI 0.541-1.121),the consistency was 88.24%on ultrasound;the Kappa value was 0.914(95%CI 0.624-1.204),the consistency was 94.12%on MRI;the sensitivity of ultrasound+MRI in the diagnosis of fetal teratoma(96.00%)was higher than that of ultrasound(64.00%),MRI(68.00%)(P<0.05).Conclusion The diagnosis of sacrococcygeal teratoma by ultrasound and MRI is consistent with the pathological results.The combination of the two can improve the sensitivity of diagnosis and provide reference for clinical decision-making.
