目的对胃癌的CT表现进行分析,以提高胃癌的临床诊断水平。方法回顾性分析32例经手术和胃镜病理证实的胃癌患者的CT表现。结果本组32例均有局部或广泛胃壁增厚的情况,其中16例腹腔淋巴结肿大,10例周围脏器侵犯,4例远处转移,2例早期。螺旋CT对胃癌病变的全貌、病变与邻近脏器的关系都能清楚地显示出来。结论螺旋CT不仅对早期的胃癌诊断具有一定的价值,而且在胃癌中晚期的定位以及定性方面的诊断价值更高。
Objective To analyze the CT features of gastric cancer in order to improve the clinical diagnosis of gastric cancer. Methods The CT findings of 32 cases of gastric cancer confirmed by operation and gastroscopy were retrospectively analyzed. Results The group of 32 cases had local or extensive gastric wall thickening. Among them, 16 cases had abdominal lymph node enlargement, 10 cases of peripheral organ invasion, 4 cases of distant metastasis and 2 cases of early stage. Spiral CT of gastric lesions in the whole picture, lesions and the relationship between the adjacent organs can be clearly demonstrated. Conclusion Spiral CT is not only valuable for the early diagnosis of gastric cancer, but also has a higher value in the diagnosis of advanced and localized gastric cancer.
