| 目的 探讨乳腺癌动态增强MRI表现与腋窝淋巴结转移的关系。方法 对79例乳腺癌患者（腋窝淋巴结转移31例、无腋窝淋巴结转移48例）的临床及动态增强MRI资料进行回顾性分析，参照乳腺影像报告和数据系统（BI-RADS）标准系统描述病变MRI表现，分析MRI表现与腋窝淋巴结转移的关系。结果 MRI显示肿块样病变71例（71/79，89.87%），病理诊断腋窝淋巴结转移27例。腋窝淋巴结转移与未转移乳腺癌病变位置差异有统计学意义（P<0.05），病变类型差异无统计学意义（P>0.05）。腋窝淋巴结转移与未转移乳腺肿块样病变边缘特征、早期强化模式及肿块最大径差异均有统计学意义（P均<0.05），病变形态、内部强化方式、延迟期时间-信号强度曲线类型差异均无统计学意义（P均>0.05）。结论 动态增强MRI显示的乳腺癌病灶位置及肿块大小、边缘特征、早期强化模式均与腋窝淋巴结转移有关。 |

| Objective To investigate the relationship of dynamic enhanced MRI findings of breast cancer and axillary lymph node metastasis. Methods Clinical and dynamic MRI data of 79 patients with breast cancer (31 with and 48 without axillary lymph node metastasis) were retrospectively analyzed. MRI findings of the lesions were systematically described according to breast imaging reporting and data system (BI-RADS) standards. Then the relationship of MRI findings and axillary lymph node metastasis were analyzed. Results MRI showed mass-like lesions in 71 cases (71/79, 89.87%), among them axillary lymph node metastasis was pathologically proved in 27 cases. There were significant differences in location of lesions between patients with or without metastasis axillary lymph node metastasis (P<0.05), while no significant difference in types of lesions was detected (P>0.05). There were significant differences in the marginal morphology, early enhancement pattern and mass maximum diameter of mass-like lesions between patients with or without axillary lymph node metastasis (all P<0.05), whereas no significant difference of lesion shape, internal enhancement mode nor delay phase time-signal intensity curve type was observed (all P>0.05). Conclusion The lesion's location, size of mass, marginal features and early enhancement patterns showed on dynamic enhanced MRI are associated with axillary lymph node metastasis of breast cancer. |
