摘　　要：目的 探讨超声、磁共振成像对乳腺癌患者腋下转移性淋巴结的诊断价值。方法 选取2020年2月至2023年2月山东省第一荣军优抚医院收治的90例乳腺癌患者作为研究对象,经病理学检查,转移性淋巴结68例,非转移性淋巴结22例。对所有患者分别进行超声联合磁共振成像检查,比较两种类型磁共振成像检查结果、超声结果。结果 转移性淋巴结超声中以2级以上血流分级为主,血流类型主要为周边型和混合型;非转移性淋巴结超声中以1~2级血流分级为主,血流类型主要为门型和分散性。转移性淋巴结与非转移性淋巴结的Adler血流分级及血流类型比较,差异有统计学意义(P<0.05)。转移性淋巴结磁共振成像中L/S>2、皮质厚度>3 mm。转移性淋巴结磁共振成像中L/S、皮质厚度、ADC值,以及边缘不规则、脂肪间隙不清晰、高DWT、强化不均、未见淋巴门占比高于非转移性淋巴结,差异有统计学意义(P<0.05)。结论 超声、磁共振成像检查可有效诊断乳腺癌患者腋下淋巴结转移,可以依据检查方法的特点为患者选择合适的诊断方法。Objective To investigate the diagnostic value of ultrasound and magnetic resonance imaging for axillary metastatic lymph nodes in patients with breast cancer.Methods A total of 90 patients with breast cancer admitted to the First Rongjun Youfu Hospital of Shandong Province from February 2020 to February 2023 were selected as the study objects.Pathological examination showed 68 cases with metastatic lymph nodes and 22 cases with non-metastatic lymph nodes.All patients were examined by ultrasound combined with magnetic resonance imaging,and the results of magnetic resonance imaging and ultrasound were compared between the two types.Results In the ultrasonography of metastatic lymph nodes,the main blood flow grade was above grade 2,and the main blood flow types were peripheral and mixed type.In the ultrasonography of non-metastatic lymph nodes,the main blood flow was grade 1-2,and the blood flow type was mainly portal and dispersed type.There were significant differences in Adler blood flow grade and blood flow type between metastatic lymph nodes and non-metastatic lymph nodes(P<0.05).In magnetic resonance imaging of metastatic lymph nodes,L/S>2,cortical thickness>3 mm.In magnetic resonance imaging of metastatic lymph nodes,L/S,cortical thickness,ADC value,and the proportion of irregular edges,unclear fat space,high DWT,uneven enhancement,no lymph portal were higher than those of non-metastatic lymph nodes,with statistical significance(P<0.05).Conclusion Ultrasound and magnetic resonance imaging examinations can effectively diagnose axillary metastatic lymph nodes in breast cancer patients,and appropriate diagnostic methods can be selected for patients based on the characteristics of the examination methods.
