目的观察彩色多普勒超声在乳腺小肿块良恶性鉴别中的应用价值。方法选取2010年5月~2014年11月收治的乳腺小肿块患者115例,经手术病理鉴别诊断,其中55例为乳腺癌(恶性组)、60例为乳腺良性肿块(良性组),对比两组的术前彩色超声成像中血流信号情况及超声诊断结果。结果恶性组的收缩期血液流速峰值明显快于良性组、阻力指数明显高于良性组,恶性组少血流信号(0~Ⅰ级)的比例明显低于良性组(P<0.05);恶性组以穿入型血流为主,良性组以环绕型血流为主,两组的血流形态学分型结果差异有统计学意义(P<0.05)。结论良恶性乳腺小肿块在彩色超声显示中具有不同的血流信号特点,血流的相关参数与定量分布情况对乳腺小肿块的良恶性鉴别具有一定的提示作用,可以辅助诊断良恶性乳腺小肿块。
Objective To observe the value of color Doppler ultrasound in the differential diagnosis of benign and malignant breast tumors. Methods One hundred and fifteen patients with small breast mass who were admitted from May 2010 to November 2014 were diagnosed by pathological diagnosis, including 55 cases of breast cancer (malignant group) and 60 cases of benign breast mass (benign group), compared with two Group of preoperative color ultrasound imaging of blood flow signals and ultrasound diagnosis. Results The peak value of systolic blood flow velocity in malignant group was significantly faster than that in benign group, and the resistance index was significantly higher in benign group than that in benign group (P <0.05). Malignant group Peripheral blood flow was the main type. Surrounding blood flow was dominant in the benign group, and there was a significant difference in morphological typing of blood flow between the two groups (P <0.05). Conclusion Small benign and malignant breast masses have different characteristics of blood flow signals in color sonographic display. The relevant parameters and quantitative distribution of blood flow have certain hints on benign and malignant lesions of small breast masses, which can be used to diagnose benign and malignant breast masses .
