彩色多普勒超声对良恶性乳腺肿块的鉴别诊断价值

The differential diagnostic value of color Doppler ultrasound for benign and malignant breast tumor

目的探讨彩色多普勒超声(彩超)对良恶性乳腺肿块的鉴别诊断价值。方法选择本院收治的183例乳腺肿块患者,采用彩色超声诊断仪观察乳腺肿块的形态、边界、包膜、内部回声、后方回声、血流、腋窝淋巴结等,并将诊断结果与病理诊断对照,观察两种诊断方法的相符率。结果彩超诊断结果显示,良恶性乳腺肿块的形态、边界、包膜、内部回声、后方回声、血流、腋窝淋巴结等影像特征差异有统计学意义(P<0.01);彩超与病理诊断结果的相符率中,乳腺癌为90.79%、乳腺纤维瘤为87.88%、乳腺增生为85.29%、乳腺炎为100.00%、乳腺囊肿为100.00%。结论彩超利用不同组织的声阻抗差异形成的微小界面成像,提高了分辨率和浅表器官穿透力,能清晰显示乳腺及胸壁组织的解剖层次,可发现直径<1.0 cm的乳腺肿块,是鉴别诊断良恶性乳腺肿块的重要方法。

Objective To investigate the differential diagnostic value of color Doppler ultrasoound for benign and malignant breast tumor. Methods 183 cases of patients with breast tumors treated in our hospital were selected,the morphology,borders,envelope,internal echo,posterior echo,blood,axillary lymph nodes of breast lumors were observed by color ultrasound diagnostic apparatus,and the ultrasound diagnosis results and pathologic diagnosis results were com- pared,the consistent rates of the two diagnostic methods were observed. Results The uhrasonography of benign and malignant breast tumors showed that the image features of morphology,boundary,envelope,internal echo,posterior echo, blood,axillary lymph nodes of benign and malignant breast tumors had significant differences （P〈0.01）.The consistent rate of color ultrasound compared with pathologic diagnosis results showed that the breast cancer,breast fibroma,breast hyperplasia,mastitis and breast cysts was 90.79%,87.88%,85.29%,100.00%,100.00% respectively. Conclusion The color Doppler ultrasound can improve resolution and superficial organ penetration,clearly shows the anatomy of the breast and chest wall tissue levels,finds the breast tumor diameter less than 1.0 cm by different organizations to form the tiny differences in acoustic impedance interface imaging,and it is an important indicator for differential diagnosis of breast tumor.
