乳腺癌声像图特征分析

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4个等级:0、Ⅰ、Ⅱ、Ⅲ级。结果恶性肿块多表现为形态不规则者60例(94%)、边界粗糙者52例(81%)、内部回声不均匀者58例(91%)、纵横比大于1者61例(95%)、后方回声衰减者56例(88%)。根据CDFI血流分流,恶性肿块血流多为Ⅱ~Ⅲ级,54例(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。

Utrasonographic feature of breast cancer

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.Then,color Doppler imaging 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 ratio1（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,which can obviously improve the diagnostic rate of breast cancer.
