彩色多普勒超声在鉴别卵巢肿瘤良恶性中的应用及意义

Application and Significance of Color Doppler Ultrasound in Differential Diagnosis of Ovarian Neoplasms

目的探讨超声在卵巢肿瘤良恶性鉴别中的应用及意义。方法回顾性分析27例卵巢肿瘤患者的彩色多普勒超声,经术后病理证实:良性17例,恶性10例。结果彩色多普勒超声显示,卵巢良恶性肿瘤的血流的分布、血流速度及血流阻力指数有一定的规律,恶性卵巢肿瘤血管多分布于肿瘤的中心部位及膈上,多为低阻型;良性肿瘤的血管多位于周边,阻力相对较高。结论将彩色多普勒超声在卵巢肿瘤血流分布情况及RI结合起来综合分析,可为卵巢肿瘤早期诊断及初步判定卵巢肿瘤的良恶性提供重要信息。

Objective To explore the application and the significance of color Doppler ultrasound in differential diagnosis between malignant and benign ovarian neoplasms. Methods 27 cases of such patients were analyzed retrospectively. Among them, benign 17 cases, malignant 10 cases which were confirmed by pathology. Results The blood stream distribution , speed of blood flow and blood resistant index （RI） of tumor have determinate regular. Malignant ovarian neoplasms vessel distribute in tumor center position and above diaphragm, many of them are low resistance. Benign tumor vessel located ambitus and high resistance. Conclusion Blood stream distribution combine with RI could perform important information for early diagnose and benign and malignant initial judgement in ovarian neoplasms.
