灰阶超声联合实时组织弹性成像诊断宫颈癌

Gray-scale ultrasound combined with real-time tissue elastography in diagnosis of uterine cervical cancer

目的探讨经阴道实时组织弹性成像对宫颈癌的诊断价值。方法对78例宫颈癌患者术前行经阴道灰阶超声及弹性成像检查,以病理诊断为金标准,分别计算各方法的敏感度、特异度和准确率。结果经阴道灰阶超声诊断宫颈癌的敏感度、特异度、准确率分别为66.67%(40/60)、55.56%(10/18)、64.10%(50/78);经阴道弹性成像诊断宫颈癌的敏感度、特异度和准确率分别为58.33%(35/60)、44.44%(8/18)、55.13%(43/78);两者联合诊断宫颈癌的敏感度、特异度、准确率分别为91.67%(55/60)、83.33%(15/18)、89.74%(70/78)。结论经阴道弹性成像是灰阶超声的良好补充,两者联合可大幅提高宫颈癌诊断准确率。

Objective To explore the value of real-time tissue elastography in the diagnosis of uterine cervical cancer.Methods Totally 78 patients with uterine cervical cancer underwent transvaginal gray-scale ultrasound and tissue elastography before operation.Taking pathologic results as gold standards,the diagnostic sensitivity,specificity and accuracy rate of each method were analyzed.Results In the diagnosis of uterine cervical cancer,the sensitivity,specificity and accuracy rate of transvaginal gray-scale ultrasound was 66.67%（40/60）,55.56%（10/18） and 64.10%（50/78）,respectively,while of transvaginal elastography was 58.33%（35/60）,44.44%（8/18） and 55.13%（43/78）,respectively.When both methods were combined,the sensitivity,specificity and accuracy rate was 91.67%（55/60）,83.33%（15/18） and 89.74%（70/78）,respectively.Conclusion Real-time tissue elastography is a good supplement to transvaginal gray-scale ultrasound.Combined with transvaginal gray-scale ultrasound can increase the diagnostic accuracy of real-time tissue elastography for uterine cervical cancer.
