| 文章摘要： | 目的 探讨乳腺癌声像图与彩色血流特征的表现。 方法 通过二维超声了解乳腺癌的形态、边界、内部回声、纵横比、有无后方回声衰减等，再辅以彩色多普勒检查，观察病灶内部及周边的血流情况，并根据血流丰富程度分四个等级:0、Ⅰ、Ⅱ、Ⅲ级。 结果 恶性肿块多表现为形态不规则占60/ 64(94%)、境界粗糙占52/64(81%)、内部回声不均匀占58 /64(91%)、纵横比＞1，61/64(95%)、后方回声衰减56/64(88%)。根据CDFI血流分流，恶性肿块血流多为Ⅱ～Ⅲ级，54 /64(84%)。结论 高频超声辅以CDFI进行乳腺恶性肿块的检测，能明显提高诊断率，为乳腺癌的早期诊断提供了有效的检查方法。 |

| 文章摘要（英文）： | Objective: To investigate the two-dimensional ultrasound and color Doppler features of breast cancer. Methods: The two-dimensional ultrasonic imaging characteristics of breast masses were analyzed， including the morphology， border， internal echo， tall to wide ratio and posterior echo attenuation of the masses. Color Doppler imaging then was used to observe the blood flow within and around the masses. According to the color Doppler imaging results， blood flow was divided into four stage: 0、Ⅰ、Ⅱ and Ⅲ. Results: Malignant tumors detected by ultrasound were more frequently found to have the following features: irregular shape (58/64， 91%)， ill-defined margin (52/64， 81%)， heterogeneous internal echo (58/64， 91%)， tall to wide ratio＞1 (61/64， 95%)， posterior echo attenuation (56/64， 88%)， and stage Ⅱ～Ⅲ of blood flow (54/64， 84%). Conclusion: High frequency ultrasound combined with color Doppler imaging is effective method to detect breast cancer in early stage， and it can obviously improve the diagnostic rate of breast cancer. |
