摘　　要：目的:探讨钼靶X线摄影与MRI联合对隐匿性乳腺癌的诊断价值。方法:回顾分析因腋窝肿块就诊,临床乳房内未触及肿块,后经腋窝肿块切除活检证实为淋巴结转移性腺癌的患者共33例,术前均行钼靶X线摄影与动态增强MRI检查。结果:MRI诊断正确30例,诊断准确率为90.91%,显示钙化4例,钙化显示率为12.12%;钼靶X线摄影诊断正确24例,诊断准确率为72.73%,显示钙化22例,钙化显示率为66.67%。两者差异均有统计学意义(P<0.01)。结论:动态增强MRI对隐匿性乳腺癌的诊断价值明显优于X线钼靶,钼靶对钙化较敏感,两者联合对早期发现、早期诊断、早期治疗隐匿性乳腺癌具有非常重要的临床意义。Objective To study the value of occult breast cancer diagnosed by dynamic contrast enhanced - MRI and digital mammogra- phy. Method Clinical data from April 2005 to April 2011 were retrospectively analyzed, and 33 cases with no palpable tumor in breast visi- ted because of the tumor in armpit,then proved to be metastasis adenocarcinoma of lymph node after the examination of the tumors cut in armpit. All cases accepted dynamic contrast enhanced - MR] and digital mammography. Results The diagnostic accuracy of occult breastcancer with MR/and digital mammography were 90. 91% （30/33） and 72.73% （24/33） （P 〈 0.01 ）, respectively. X - ray showed calci- fications （ n = 22） while MR/showed calcifications （ n = 4 ）. Conclusion Dynamic contrast enhanced - MR/is superior to digital mammog- raphy in the diagnosis of occult breast cancer, but inferior in the sensitivity of calcification. So dynamic contrast enhanced - MR/united with digital mammography will play a significant role in the diagnosis of occult breast cancer.
