目的讨论螺旋CT在胃癌淋巴结转移中的应用,以及CT下的病理特征。方法回顾胃癌患者53例,术前常规螺旋CT检查,观察影像学特征,与病理结果进行对照。结果经CT共检查出淋巴结563个,发生转移的106个(18.8%),长径大,边缘规则不光滑、不均匀强化的淋巴结发生转移的几率更大,正常淋巴结细胞短径、长径、CT值更低,P<0.05,有统计学意义。以上结果与术后病理检查符合。结论对胃癌患者进行螺旋CT检查,通过对淋巴结是否发生转移进行分析后制订相应的手术方案,为手术成功提供理论依据。
Objective To discuss the application of spiral CT in lymph node metastasis of gastric cancer and the pathological features under CT. Methods A retrospective analysis of 53 patients with gastric cancer, preoperative routine spiral CT examination to observe the imaging features, and pathological results were compared. Results There were 563 lymph nodes and 106 metastases (18.8%) were detected by CT. The longer the diameter of the lymph nodes, the more irregular the edges, the more heterogeneous lymph nodes metastasized. The short, long, CT value is lower, P <0.05, with statistical significance. The above results are consistent with postoperative pathological examination. Conclusion Spiral CT examination of gastric cancer patients, through the analysis of lymph node metastasis after the development of the corresponding surgical options, to provide a theoretical basis for the success of the operation.
