摘　　要：目的探讨磁共振联合彩超在胎儿胆囊异常中的诊断价值。方法回顾性分析2013年1月~2018年12月于我院门诊进行产前检查孕妇8200例,均采用常规产前彩色多普勒超声检查、磁共振(MRI)及产后彩超检查,诊断胎儿的胆囊状况,分析比较彩超、MRI检查及两者联合检查的临床检出率、诊断价值。结果产后超声检查确诊胎儿胆囊异常58例。彩超、MRI及二者联合检查胎儿胆囊异常病变类型的准确度比较,差异无统计学意义(P>0.05),但联合检查的结果与孕后检验结果最接近,准确性最高。灵敏度方面,彩超、MRI以及二者联合三者比较差异无统计学意义(P>0.05),MRI联合彩超检查特异性、阳性预测值及阴性预测值显著高于单纯彩超或MRI检查,比较差异有统计学意义(P<0.05)。结论彩超联合MRI共同诊断能清晰反应胎儿胆囊状况,异常情况检出率较高,可以取得良好的效果,使漏诊以及误诊率明显降低,两者联合可以作为诊断胎儿胆囊异常的重要手段,适宜临床应用推广。Objective To explore the diagnostic value of magnetic resonance combined with color Doppler ultrasonography in fetal gallbladder abnormalities.Methods 8200 pregnant women who underwent prenatal examinations in our hospital from January 2013 to December 2018 were retrospectively analyzed.All of them were examined by conventional prenatal color Doppler ultrasonography,magnetic resonance imaging(MRI)and postpartum color Doppler ultrasonography to diagnose the gallbladder condition of the fetus.The clinical detection rate and diagnostic value of color Doppler ultrasonography,magnetic resonance imaging and combined examinations were analyzed and compared.Results Postpartum ultrasonography confirmed 58 cases of fetal gallbladder abnormalities.There was no statistically significant difference in the accuracy of color Doppler ultrasonography,MRI and combined examination in diagnosis of fetal gallbladder abnormalities(P>0.05).But the results of combined examination were the closest to the results of the post-pregnancy test,with the highest accuracy.In terms of sensitivity,there was no statistically significant difference among color Doppler ultrasound,MRI and their combination examination(P>0.05).The specificity,positive predictive value and negative predictive value of combined MRI and color Doppler ultrasound were significantly higher than those of simple color Doppler ultrasound or MRI.The comparative differences were statistically significant(P<0.05).Conclusion The combined diagnosis of color Doppler ultrasonography and MRI can clearly reflect the condition of fetal gallbladder and the detection rate of abnormal condition is high.It can achieve good results and significantly reduce the rate of missed diagnosis and misdiagnosis.The combination of color Doppler ultrasonography and MRI can be used as an important means to diagnose abnormal gallbladder of fetus,which is suitable for clinical application and promotion.
