摘    要:目的:探讨良恶性乳腺肿块二维声像图和彩色多普勒血流状况及病理基础。方法:85例乳腺肿块级二维超声了解其形态、边界,边缘、内部回声,有无后方衰减及侧方声影等。然后用彩色多普勒检查,观察肿块内部及周边血流情况。结果:在乳腺肿块声像图诊断中,以边界回声特征最为重要,它是肿块良,恶性鉴别的关键。本组大多数恶性肿块形态不规则,边界不清,内部回声不均,同时彩色多普勒检出丰富血流信号,乳腺癌多表现为肿块前,侧缘有不规则强回声(恶性晕),这与癌组织浸润和周围纤维组织增生有关;良性肿瘤多表现为边界光滑,侧缘回声减弱,这与良性肿瘤呈膨胀性生长有完整包膜有关,结论:二维及彩色多普勒诊断乳腺良恶性肿瘤,符合率较高,具有较大的临床应用价值。

关 键 词:乳腺肿块  二维超声  彩色多普勒  超声诊断  病理  乳腺肿瘤

Two-dimentional Ultrasound and Color Doppler Flow Imaging Diag nosis of Breast Lumps with Pathologic Bases
Abstract:Objective:To study two dimentional ultrasound and color Doppler flow imaging in the breast lumps with pathologic bases.Methods:Eighty five cases with breast lumps were examined by B mode ultrasound to observe the shape,border and inside echoes of breast lumps,whether there were rear attenuation and lateral shadowing,and to survy inside and peripheral blood flows by color Doppler ultrasonography.Results:Edge echoes were the most important characteristics in diagnosis of breast lumps and the keys to differentiate benign and malignant ones.Most malignant lumps in our cases were with irregular shape,indistinct border,irregular inside echoes and plentiful blood flow signals.Irregular echo enhancements in anterior and lateral borders(malignant haloes)were shown in most mammary cancers.These changes might be associated with the infiltrative growth of cancers and hyperplasia of fiberous tissues.In benign tumors,smooth edges and lateral echo attenuation were demonstrated because of expansible growth in an intact membrane.Conclusions:Two dimensional ultrasound and color Doppler flow imaging possess clinical practical value to get a high accurate diagnostic rate of breast neoplasms.
Keywords:Breast lump  B  mode ultrasound  Color Doppler flow imaging
