目的 分析胃癌在 Ｃ Ｔ中的不同表现以提高 Ｃ Ｔ 对胃癌诊断价值的认识。方法 ４９ 例患者经手术和（或）内镜病理证实为胃癌。按常规行胃部 Ｃ Ｔ 扫描检查，检查前空腹状态下服水约 ８００～１ ５００ ｍ ｌ，检查前 １０ ｍ ｉｎ肌注 ６５４２ ２０ ｍ ｇ，作增强前后扫描。结果 胃壁增厚 １～２ ｃｍ ，范围＜ ５ ｃｍ 者 ５ 例，胃壁增厚＞ ２ ｃｍ 伴有局限肿块 ２１ 例，胃壁增厚＞ ２ ｃｍ 伴有广泛（环形）肿块 ２３ 例，邻近器官侵犯 ３８ 例，淋巴结转移 ２５ 例。 Ｃ Ｔ 对病变的检出率１００％ ，定性准确率 ９６．１％ 。结论 Ｃ Ｔ 对进行性胃癌的诊断有其独到之处，对外科术前选择合适的手术方法和术后的治疗起着重要的作用。
Objective To analyze the different manifestations of gastric cancer in C T in order to improve the understanding of the diagnostic value of C T in gastric cancer. Methods 49 cases of patients with gastric cancer by surgery and / or endoscopic pathology. According to the routine gastric C T-scan examination, check before the fasting state of service water about 800 ~ 1500 m l, 10 m in muscle before the examination 654 2 20 m g, before and after enhanced scanning. Results The gastric wall thickening of 1 ~ 2 cm, the range of 5 cm in 5 cases, gastric wall thickening> 2 cm with localized mass in 21 cases, gastric wall thickening> 2 cm with extensive (annular) mass in 23 cases, the adjacent organ invasion 38 Cases, lymph node metastasis in 25 cases. The detection rate of CT was 100%, and the qualitative accuracy rate was 96.1%. Conclusions C T has its own uniqueness in the diagnosis of progressive gastric cancer. It plays an important role in the surgical selection of appropriate surgical methods and postoperative treatment.
