二维超声及彩色多普勒联合应用对卵巢肿瘤的诊断

目的：探讨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114例137个卵巢肿瘤进行腹部二维超声及彩色多普勒检测，并对比良、恶笥肿瘤形态、包膜、腹水、周边及内部血流值。结果：良、恶性肿瘤的形态、包膜有明显差异。有51％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15％，恶性肿瘤为68％。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良、恶性卵巢肿瘤的有效方法。

Differential Diagnosis of Ovarian Neoplasms by Way of Integration of 2-D Doppler Ultrasound with Color Doppler Technique

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 one hundred and fourteen patients with 127 ovarian neoplasms were examined by combination of two-dimensional Doppler ultrasound and color Doppler technique.The configuration,integument,ascites,peripheral and internal blood stream between benign and malignant neoplasms were compared.Results:The differences of the configurations and integuments between benign and malignant neoplasns were significant.The ascites could be detected in 51% of patients with malignant neoplasms,and in less than 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 wree 15% and 68%,respectively.Conclusions:Ultrasonic morphology,intratumoral arterial resistance index(RI)and pulsatility index(PI)detected from color Doppler are useful for differential diagnosis of ovarian neoplasms.
