摘　　要：目的 探讨彩超联合核磁共振对乳腺癌淋巴结转移的诊断效果。方法 选取我院2008年5月-2014年5月收治的497例乳腺癌患者,比较其术前彩超、核磁共振及二者联合诊断与术后病理诊断的符合情况。结果 彩超检查共发现淋巴结转移322例,无转移175例,彩超检查对乳腺癌淋巴结转移诊断的灵敏度为94.1%（303/322）,特异性为35.4%（62/175）,总体符合率为73.4%（365/497）;核磁共振检查共发现淋巴结转移397例,无转移100例,核磁共振检查对乳腺癌淋巴结转移诊断的灵敏度为99.2%（394/397）,特异性为78.0%（78/100）,总体符合率为95.0%（472/497）;联合检查共确诊淋巴结转移真阳性399例,假阴性6例,真阴性82例,假阳性10例,灵敏度为98.5%（399/405）,特异性为89.1%（82/92）,总体符合率为96.8%（481/497）。结论 彩超联合核磁共振在乳腺癌淋巴结转移的诊断中具有补充作用,可弥补单一诊断的缺陷,达到更佳的诊断效果,且更准确,对制定临床治疗方案具有重要意义。Objective To investigate the value of color doppler ultrasound combined with MRI in the diagnosis of lymph node metastasis of breast cancer. Methods 497 cases of breast cancer that were hospitalized between May 2008 and May 2014 were selected out. Comparison was made between the preoperative color Doppler ultrasound, MRI examination, and the combined diagnosis by the two and the postoperative pathological diagnosis of compliance.Results The color Doppler ultrasound showed lymph node metastasis in 322 cases, and 175 cases had no metastasis. The sensitivity of color Doppler ultrasound in the diagnosis of lymph node metastasis of breast cancer was 94.1% （303/322）; the specificity was 35.4% （62/175）; and the total coincidence rate was 73.4% （365/ 497）. MRI showed lymph node metastasis in 397 cases, and 100 cases had no metastasis. The sensitivity, specificity, and the total coincidence rate of MRI was 99.2% （394/397）, 78.0%（78/100）, and 95.0%（472/497）, respectively. The joint inspection showed true positive lymph node metastasis in 399 cases, false negative metastasis in 6 cases, true negative in 82 cases, and false positive in 10 cases. The sensitivity, specificity, and the total coincidence rate was 98.5% （399/405）, 89.1% （82/92）, and 96.8% （481/497）, respectively. Conclusion Color Doppler ultrasound combined with MRI plays a supplementary role in the diagnosis of lymph node metastasis of breast cancer. The joint inspection can remedy the defects of the single diagnosis and achieve better diagnostic effects with more accuracy. It has great importance in the establishment of the clinical treatment plan.
