目的：探讨经阴道结合经腹部二维超声及彩色多普勒鉴别卵巢良、恶性肿瘤的特点及意义。方法对120例142个卵巢肿瘤进行二维及彩色多普勒超声检测，并对比良、恶性肿瘤形态、包膜、内部回声、腹水、周边及内部血流值。结果良、恶性的形态、包膜及内部回声有明显差异。有50%的恶性肿瘤可测出腹水，而良性者不足2%。两者间周边血流无显著差异，而内部血流差异具有显著性意义；良性肿瘤为18%，恶性肿瘤70%。结论超声形态学和彩色多普勒探测肿瘤动脉阻力指数是鉴别卵巢良、恶性肿瘤的有效方法。“,”Objective To investigate the value of differential diagnosis of ovarian neoplasms by way of integration of two-dimensional Doppler ultrasound with color Doppler technique. Methods A total of 120patients with 142 ovarian neoplasms were examined by combination of two-dimensional Doppler ulteasound and color Doppler technique.The configuration,integument,ascites,peripheral and internal blood stream between benign and malignant neoplasns were compared. Results The differences of the configurations and integuments between benign and malignant neoplasns were significant.The ascites could be detected in 50% of patients with malignant neoplasms,and in less then 2% of patients with benign neoplasms. No significant differences in the peripheral blood streams,but significances were shown in the internal blood streams.The display rates of patients with benign neoplasms and malignant neoplasms were 18% and 70%,respectively. Conclusion Ultrasonic morphology,intratumoral arterial resistance index(RI) detected from color Doppler are useful for differential diagnosis of ovarian neoplasms.
