目的 分析螺旋CT对正常人与胃癌患者淋巴结检出情况。方法 对 88例正常人和 10 6例胃癌患者进行上腹部螺旋CT扫描 ,比较淋巴结检出情况。结果 正常组与胃癌组间淋巴结检出情况有显著差异。螺旋CT对淋巴结总检出率为 3 9.7% ,转移阳性淋巴结检出率达 69.2 %。结论 淋巴结密度增高对CT淋巴结检出率有重要影响 ,淋巴结CT检出率与胃癌具有明显相关性 ,对胃癌淋巴引流区域检出的淋巴结必须给予高度重视
Objective To analyze the detection of lymph nodes in normal and gastric cancer patients by spiral CT. Methods 88 cases of normal and 106 cases of gastric cancer patients were spiral CT scans, lymph node detection were compared. Results There was a significant difference in the detection of lymph nodes between normal group and gastric cancer group. Spiral CT of the lymph node detection rate of 3 9.7%, positive lymph node metastasis detection rate of 69.2%. Conclusion The increased lymph node density has an important effect on the detection rate of CT lymph nodes. The detection rate of CT in lymph nodes is significantly correlated with gastric cancer, and the lymph nodes detected in lymph drainage area of gastric cancer must be given high priority
