彩色多普勒超声在诊断卵巢肿瘤中的应用

Color Doppler ultrasound in the diagnosis of ovarian tumors

目的:探讨经阴道彩色多普勒超声鉴别良、恶性卵巢肿瘤的价值。方法:对82例卵巢肿瘤患者行经腹部彩色多普勒超声(TAS-CD)和经阴道彩色多普勒超声(TVS-CD)检查,观察其二维及彩色多普勒声像图特征。结果:82患者共91个病灶,恶性组37例41个病灶,对照组45例50个病灶。病灶内血流RI<0.4恶性组和对照组分别为37个和6个病灶,PI<1.0分别为34个和9个病灶。以RI<0.4和PI<1.0鉴别卵巢良恶性肿瘤,其敏感性、特异性分别为90.24%、90.00%和82.93%、82.00%。术前超声正确诊断恶性病灶35个,对照组43个,超声诊断卵巢恶性肿瘤的准确性、敏感性和特异性分别为85.7%、85.4%和86.0%。阳性预测值和阴性预测值分别为83.3%和87.8%。结论:超声是鉴别良恶性卵巢肿瘤的有效方法,厚壁、RI和PI是重要指标。

Objective To study the value of transvaginal color Doppler ultrasound（TVS-CD） in differentiating benign and malignant ovarian tumors.Method Total 82 patients with ovarian tumor had undergone TVS-CD and TAS-CD were observed its two dimension and colour Doppler ultrasonic features.Results For 82 patients with 91 lesions,including 37 cases 41 malignant lesions（the malignant group） and 45 cases 50 benign lesions（the control group）.RI0.4 in the malignant group and the control group were 37 lesions and 6 lesions,PI1.0 were 34 lesions and 9 lesions.RI 0.4 and PI1.0 identifying the benign and malignancy ovarian tumor,the sensitivity and specificity were 90.24%,90.00% and 82.93%,82.00%,respectively.For 35 malignant lesions and 43 lesions of the control group were diagnosed correctly by preoperative ultrasonography.The accuracy,sensitivity and specificity of ultrasound diagnosis of malignant ovarian were 85.7%,85.4% and 86.0%,respectively.The positive predictive value and negative predictive value were 83.3% and 87.8%,respectively.Conclusion Ultrasonography is useful for differential diagnosis of ovarian neoplasms,and thick of wall,RI and PI are important indexes.
