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。
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 diag- nosis was compared with the histopathology after operation. Results The sensitivity and specificity of malignant ovar- ian 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 di- agnostic 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.
