【摘要】:目的探讨MRI对乳腺癌患者腋窝淋巴结转移的鉴别诊断价值。方法分析经病理证实并行腋窝MR扫描的44例乳腺癌患者资料,分析MRI表现,包括淋巴结长径、短径、皮质厚度、ADC值、淋巴门情况、淋巴结边缘、周围脂肪间隙情况、DWI信号、强化方式及时间—信号强度曲线等,并绘制的ROC曲线分析淋巴结长径、短径、皮质厚度、ADC值对腋窝淋巴结转移的诊断效能。结果病理结果显示有淋巴结转移者24例(24/44,54.55%),无淋巴结转移者20例(20/44,45.45%),两者淋巴结长径、短径、皮质厚度、ADC值、淋巴门是否消失、淋巴结边缘、周围脂肪间隙、DWI信号、强化方式差异均有统计学意义(P均0.05)。淋巴结长径、短径、皮质厚度及ADC值的ROC曲线下面积分别为0.797、0.765、0.848、0.749。结论 MRI在鉴别乳腺癌腋窝淋巴结状态中有重要价值,皮质厚度大于0.54cm高度提示腋窝淋巴结转移。
[Abstract]:Objective to evaluate the value of MRI in differential diagnosis of axillary lymph node metastasis in breast cancer. Methods the data of 44 patients with breast cancer confirmed by pathology and axillary Mr scan were analyzed. The MRI findings, including lymph node length, short diameter, cortical thickness, lymphatic hilum, lymph node margin and peripheral fat space, were analyzed. The enhancement mode and the time-signal intensity curve were used to analyze the diagnostic efficacy of the long diameter, short diameter and cortical thickness of lymph nodes in the diagnosis of axillary lymph node metastasis. Results the pathological results showed that 24 cases had lymph node metastasis (24 / 44) 54.55% and 20 cases had no lymph node metastasis (20% 44.45%). Both lymph nodes had long diameter, short diameter, cortical thickness and ADC value, lymphoid hilum disappeared, lymph node margin, peripheral fat space and DWI signal. There were significant differences in the reinforcement patterns (P < 0.05). The area under the ROC curve of long diameter, short diameter, cortical thickness and ADC value of lymph nodes were 0.7970.765U 0.848c0.749, respectively. Conclusion MRI plays an important role in differentiating axillary lymph node status of breast cancer. The thickness of cortex is higher than that of 0.54cm suggesting axillary lymph node metastasis.
