MRI诊断剖宫产术后子宫疤痕妊娠的应用价值分析

Application value of MRI in the diagnosis of cesarean scar pregnancy after cesarean section

目的分析磁共振成像(MRI)诊断剖宫产术后子宫疤痕妊娠(CSP)的应用价值。方法将2013年9月至2016年10月我院收治的27例子宫疤痕妊娠患者作为研究对象,同时进行阴道彩超检查及MRI检查,对其超声及MRI图像进行分析,将所得结果与手术病理及临床证实结果比较,比较两种检查方法的诊断准确率。结果对CSP患者采用MRI诊断的准确率明显高于阴道彩超,差异有统计学意义(P<0.05);MRI对妊娠部位分型诊断的敏感性为100.0%,特异性为100.0%,阴道彩超对妊娠部位分型诊断的敏感性为86.21%,特异性为50.00%,差异有统计学意义(P<0.05)。结论 MRI检查具有软组织分辨率高、多平面成像、无损伤性等优点,对于CSP诊断的准确率以及妊娠部位分型诊断的敏感性都极高,有效避免了由于误诊及漏诊造成的不良妊娠结局,具有重要的临床应用价值。

Objective To analyze the application value of magnetic resonance imaging(MRI)in the diagnosis of cesarean scar pregnancy(CSP)after cesarean section.Methods A total of 27 cases patients with CSP were included in this study from September 2013 to October 2016.Transvaginal color doppler ultrasonography and MRI examination of all patients were carried out to analyze the ultrasonography and MRI images,and the results were compared with the surgical pathology and clinical confirmed results.The diagnostic accuracy of the two methods was compared.Results The diagnostic accuracy of MRI was significantly higher than that of transvaginal color doppler ultrasonography in patients with CSP(P<0.05).The sensitivity and specificity of MRI in typing diagnosis of pregnancy was 100% and 100%,while the sensitivity and specificity of transvaginal color doppler ultrasonography in typing diagnosis of pregnancy was 86.21% and 50.00%(P<0.05).Conclusion MRI examination has the advantages of high soft tissue resolution,multi planar imaging,no damage and so on.The diagnosis accuracy of CSP and the sensitivity of typing diagnosis of pregnancy is very high,to effectively avoid the adverse pregnancy outcome by misdiagnosis and missed diagnosis.It has an important clinical application value.
