摘　　要：目的探讨超声联合MRI检查在诊断胎儿泌尿系统异常中的应用价值。方法回顾性分析经产前超声可疑胎儿泌尿系统异常的647例胎儿的临床资料,孕妇均在超声检查后2d内行MRI检查。以病理和随访为金标准,分析超声、MRI对胎儿泌尿系统异常检出准确率及影像特征。结果600例经病理及随访证实中,MRI、超声及两者联合诊断胎儿泌尿系统异常的准确率分别为96.50%、96.67%、97.00%,敏感度分别为95.28%、96.23%、98.11%,特异度分别为96.76%、96.76%、96.76%。MRI、超声及两者联合诊断在准确率、敏感度、特异度、阳性预测值及阴性预测值差异均无统计学意义(P>0.05)。MRI、超声及两者联合诊断胎儿泌尿系统异常的曲线下面积(AUC)分别为0.960、0.965、0.974,两两比较差异均无统计学意义(P>0.05)。结论与产前超声检查相比,MRI在诊断胎儿泌尿系统异常中亦具有较高准确率(96.50%),可作为产前超声检查以外的重要补充手段。Objective To investigate the application value of ultrasound combined with MRI in the diagnosis of fetal urinary system abnormalities.Methods The clinical data of 647 cases of fetal urinary system abnormalities suspected by prenatal ultrasound were ana-lyzed retrospectively.All pregnant women underwent MRI examination within 2 days after ultrasound examination.Using pathology and follow-up as the gold standard,the accuracy and imaging features of ultrasound and MRI in detecting fetal urinary system abnor-malities were analyzed.Results Among 6oo cases confirmed by pathology and follow-up,the accuracy of MRI,ultrasound and com-bined diagnosis of fetal urinary system abnormalities were 96.50%,96.67%,97.00%,sensitivity were 95.28%,96.23%,98.11%,and specificity were 96.76%,96.76%,96.76%,respectively.There were no significant differences in accuracy,sensitivity,specificity,positive predictive value and negative predictive value between MRI,ultrasound and combined diagnosis(P>0.05).The area under the curve(AUC)of MRI,ultrasound and combined diagnosis of fetal urinary system abnormalities were 0.960,0.965 and 0.974,respectively,with no statistical significance(P>0.05).Conclusion Compared with prenatal ultrasound,MRI also has a higher accuracy(96.50%)in the diagnosis of fetal urinary system abnormalities,and can be used as an important supplement to prenatal ultrasound.
