| 摘要目的：通过对直肠癌患者原发肿瘤周围脂肪间隙内淋巴结的影像学分析，来评价64 排增强螺旋CT对直肠癌淋巴结转移的
诊断价值。方法：收集我院经术后病理证实的102 例直肠癌患者的临床及影像学资料进行回顾性分析，通过多平面成像，记录直
肠周围脂肪间隙内淋巴结的CT 表现，包括淋巴结大小、边缘及强化程度。以病理结果为准确定转移性和非转移性淋巴结，采用双
盲法。结果：单因素分析结果显示淋巴结大小、边缘及强化方式与阳性率有显著的相关性（P＜ 0.05），多因素分析结果显示各相关
因素有显著诊断意义的是淋巴结大小、边缘及强化方式，其敏感性分别为94.7%、87.6%、56.9%，特异性分别为69.3%、51.6%、
62.3%。结论：综合分析原发肿瘤周围脂肪间隙内淋巴结的表观情况，有助于提高对淋巴结转移的判断。 |

| ABSTRACT Objective:By analyze of peripheral fat gap within the lymph nodes in patients with rectal cancer and evaluate 64-detector
row value of enhance spiral computed tomography in the diagnostic of lymph node metastasis of rectal cancer.Methods: To
retrospective analyze 102 cases of colorectal cancer patients, whose clinical and radiographic data are complete, which was confirmed by
postoperative pathology. Then, Proceed multi-planar reformation and record the apparent situation of the rectal around fat gap within
lymph nodes of CT performance (including lymph nodes size, and edge and strengthened) by blindly method. Results:Single factor
analysis showed that the number, size, edge of lymph nodes within the lymph nodes metastasis is significant positive correlation (P<0.05),
Multi-factor analysis of related factors have significant diagnostic significance is the lymph node size, edge and reinforcement method,
and the sensitivities were 94.7%, 87.6%, 56.9%, specificities were 69.3%, 51.6% and 62.3%. Conclusion:Comprehensive analysis of
the primary tumor surrounding lymph node apparent helps to improve the judgment of lymph node metastasis. |
