【摘要】 目的 探讨二维及彩色多普勒超声在乳腺肿块鉴别诊断方面的临床应用价值。方法 对106例经手术病理证实的乳腺肿块病例的二维及彩色多普勒超声表现与病理结果进行回顾性对比分析。结果 在乳腺肿块的声像图诊断中，以形态、边界特征最为重要，它是肿块良、恶性鉴别的关键，大多数良性肿块表现为形态规则、边缘整齐光滑、有完整包膜、内部回声均匀、后方回声增强；而大多数恶性肿块表现为形态不规则、边缘粗糙、边界不清、内部回声不均匀、后方回声衰减。恶性肿块的血流显示率明显高于良性肿块，血流分布以Ⅱ、Ⅲ级为主，良性肿块则以0、Ⅰ级为主。结论 乳腺肿块的超声诊断应以二维声像图为基础,同时结合彩色多普勒血流丰富程度，两者联合应用可提高超声对乳腺肿块的诊断符合率。

    【Abstract】 Objective To evaluate the Clinical value of two-dimensional ultrasound and color Doppler flow imaging (CDFI) for the differential diagnosis for breast masses.Methods Two-dimensional ultrasound and CDFI findings were reviewed and compared with pathological study in 106 cases with confirmed breast masses.Results Shape and edge echoes were the most important characteristics in diagnosis of breast masses and the keys to differentiate benign and malignant ones.Most benign masses were with regular shape,smooth edges and intact membrane,with homogeneous internal echo and posterior enhancement,whereas malignant masses with irregular shape,indistinct border,heterogeneous internal echo and posterior attenuation.The gradeⅡ,Ⅲvascular distribution on CDFI were usually found in malignant masses,while the grade 0,Ⅰwere found in benign ones.Conclusion The diagnosis standard of the breast masses must depend on the two-dimensional ultrasound combined with the density of the flow signals in CDFI.Combination of two-dimensional ultrasound and CDFI can increase the accuracy rate of diagnosing the breast masses. ......
