彩色多普勒超声在诊断乳腺恶性肿瘤中的价值

The value of doppler ultrasound for diagnosis of breast malignant tumor

目的探讨彩色多普勒超声在诊断乳腺恶性肿瘤中的作用。方法总结182例乳腺恶性肿瘤的二维及彩色多普勒超声检查血流显像（CDFI）信号的形态和数量、血流峰值及阻及阻力指数与病理学类型的关系。结果浸润性导管癌CDFI血流显像主要表现为内部血流、血流峰值和血流阻力均高于其他类型乳癌。其中导管原位癌主要表现为0级血流;髓样癌主要表现为Ⅰ级穿入血流（89.5%）;粘液癌主要表现为0～Ⅰ级穿入血流（93%）;炎症性乳癌表现为Ⅰ～Ⅱ级的周边血流（89%）和内部血流（93%）两种血流状态共存。浸润性导管癌肿块内CDFI血流峰值和阻力指数均高于导管原位癌、髓样癌和粘液癌,低于炎性乳癌,其差异具有统计学意义（P〈0.05）。结论乳腺癌超声显像具有特征性表现,通过恶性肿瘤的二维超声特点和彩色多普勒可初步明确乳癌的组织学类型,对乳腺恶性肿瘤的诊断具有重要价值。

Objective To investigate the role of doppler ultrasound for diagnosis of breast malignant tumor. Methods To summarize me relationship between the shapes, quantities, peak values of blood flow and index of force of resistance and pathology types in 182 patients suffered, breast malignant tumor. Results The blood flow,peak values of blood flow and index of force of resistance in infitrating duetal carcinoma were higher than those of other types of breast malignant tumor. 0 level blood flow is mainly in ductal carcinoma in situ and Ⅰ level penetration blood flow in carcinoma medullare（89.5% ） and 0 - Ⅰ level penetration blood flow in areolar cancer（93% ）and Ⅰ - Ⅱ level perimeter blood flow（ 89% ）and inner blood flow（93% ）both in inflammation breast cancer, peak values of blood flow and index of force of resistance of CDFI in iniltrating ductal carcinoma were higher than those of ductal carcinoma in situ, carcinoma medullare and areolar cancer and lower than those of inflammation breast cancer（P〈0. 05）. Conclusion Ultrasonic imaging of breast cancer has distinct characteristic which can initially to identify the pathology type of tumorand make a important value to diagnose mammary gland malignant tumor.
