目的:探讨经阴道彩色多普勒超声在子宫内膜病变中诊断价值.方法:选取本院2013年10月—2014年12月诊治的子宫内膜病变患者136例,行经腹彩色多普勒超声检查和经阴道彩色多普勒超声检查,与病理结果相比,分析诊断价值.结果:经阴道彩色多普勒超声检查的准确率(96.3%)明显高于经腹彩色多普勒超声检查(62.5%),(P<0.05).恶性病变患者存在血流信号,动脉阻力指数较良性病变更低,(P<0.05).结论:经阴道彩色多普勒超声是子宫内膜病变的有效诊断方法,具有较高的准确度,值得临床推广使用.“,”Objective To investigate diagnostic value of transvaginal color doppler ultrasound in diagnosis of endometrial lesions. Methods 136 patients with endometrial lesions were selected in hospital from October 2013 to December 2014, who treated abdominal color doppler ultrasound examination and transvaginal color doppler ultrasound examination. Compared with pathological results, diagnostic value was analyzed.Results The accuracy of transvaginal color doppler ultrasound (96.3%) was significantly higher than abdominal color doppler ultrasound (62.5%), (P <0.05). Patients with malignant lesion had blood flow signal. Arterial resistance index in malignant lesion was lower than benign lesion(P <0.05).Conclusion Transvaginal color doppler ultrasound is effective diagnostic method in endometrial lesions, which has higher accuracy. That is worthy of clinical application.
