Abstract
Objective To evaluate the value of contrast-enhanced ultrasound in the differentiation diagnosis of benign and malignant axillary lymph nodes in breast cancer.Methods The clinical data in 72 enlarged axillary lymph nodes from 50 patients with breast cancer were analyzed retrospectively.According to the lymph node pathological re-sults,72 axillary lymph nodes were divided into the benign group(n=30)and the metastatic group (n=42).The re-sults of conventional ultrasound examinations and contrast-enhanced ultrasound examination were collected and ana-lyzed.Results The long diameter/short diameter(L/S)ratio in the metastatic group was significantly less than that in the benign group (P < 0.05 ).The blood flow distribution patterns had statistical difference between the two groups (P <0.05).In the benign group,the main blood flow pattern was portal type and the main contrast enhance-ment pattern was central homogeneous enhancement,while in the metastatic group,the main blood flow patterns were peripheral or mixed types and the main contrast enhancement patterns were peripheral or mixed type,the differences between the two groups were statistically significant.The contrast enhancement time in the metastatic group was greater that that in the benign group (P <0.05).Conclusion The contrast-enhanced ultrasound imaging can better replenish the insufficiency of convention ultrasound imaging and significantly improves the ability to identify benign and malignant axillary lymph nodes in breast cancer.关键词
