| ［摘要］ 目的 探讨经阴道彩色多普勒超声（TVS-CD）对卵巢肿瘤良恶性鉴别的意义。方法 TVS-CD检测92例卵巢实性或囊实性肿块的二维灰阶图像特点及血流动力学，与术后病理对照。结果 71例引出动脉血流肿块中以阻力指数（RI）<0.5作为恶性肿瘤的诊断标准，其诊断的敏感性为96.6%，特异性为93.3%。92例肿块中以RI<0.5作为诊断标准，加用二维灰阶超声标准，诊断的敏感性为90.0%，特异性为90.3%。结论 RI能提高超声对恶性卵巢肿瘤的诊断率，经阴道彩色多普勒超声对鉴别卵巢肿瘤良恶性具有重要的临床意义。 |

| ［Abstract］ Objective To evaluate the application of transvaginal color Doppler ultrasonography (TVS-CD) in differential diagnosis of benign and malignant ovarian tumor.Methods A total of 92 cases with solid and cystic-solid mixed ovarian masses were performed transvaginal color Doppler ultrasonographic examination and the characteristic of gray-scale sonogram and haemodynamics of the tumor arteries were analyzed. The sonographic diagnosis was compared with the histopathology after operation. Results The sensitivity and specificity of malignant ovarian tumors with diagnostic criteria of resistance index (RI)<0.5 for 71 cases which demonstrated tumor arteries were 96.6% and 93.3%, respectively. And the diagnostic sensitivity and specificity of malignant ovarian tumors with diagnostic criteria of RI<0.5 for all of 92 cases were 90.0% and 90.3%, respectively. Conclusion The parameter of RI may improve the diagnosis of malignant ovarian tumor. And the TVS-CD is a useful technique in differential diagnosis of benign and malignant ovarian tumor. |
