摘要
目的探讨超声及MRI诊断胎儿肺隔离症的临床应用价值。方法对12例产前超声怀疑胎儿肺隔离症者,24h内进行MRI检查,诊断结果均经尸检病理及产后随访证实。对12例胎儿的超声和MRI图像资料进行分析,并与随访结果对照。结果产前超声诊断的12例胎儿肺隔离症,超声诊断符合率83.3%,误诊2例,(1例为隔疝,1例为肺囊腺瘤);产前MRI检查诊断准确率为91.7%,误诊1例(隔离肺误诊为腹腔肿瘤)。结论产前超声检查是诊断胎儿肺隔离症主要筛选方法,MRI可以作为胎儿超声检查的重要补充,二者联合应用,可进一步提高该病的诊断率。
Objective To study the clinical value of ultrasound （US） and magnetic resonance imaging （MRI） in the diag- nosis of fetal pulmonary sequestration. Methods Twelve pregnant women suspected fetal pulmonary sequestration re- ceived MRI examination within 24 hours after ultrasound, confirmed by autopsy or follow up. The results of prenatal ul- trasound and MRI were analyzed. Results The diagnostic accuracy of ultrasound was 83.3%, 2 cases were misdiagnosed, the diagnostic accuracy of MR was 91.7%, 1 case was misdiagnosed. Conclusion Prenatal ultrasound is the primary screening method for pulmonary sequestration, MRI can serve as a supplement, the combination of US and MRI can fur- ther improve the diagnostic accuracy of the disease.
