【摘要】 目的 :探讨胃低张螺旋CT扫描诊断胃癌的价值。方法 :47例胃癌患者 ,扫描前 10min肌注 6 5 4 2 10～ 2 0mg后 ,即饮水或 1.5 %～ 2 .0 %的泛影葡胺 80 0～ 12 0 0ml。所有患者行螺旋CT常规扫描 ,其中 39例经肘静脉团注法注入 76 %安其格拉芬 80～ 90ml行增强扫描。结果 :47例患者均能清晰显示胃癌的部位、范围、大小、周围组织侵犯及局部淋巴结转移情况。胃癌病灶表现为局限或广泛不规则胃壁增厚、僵直、胃腔缩小及软组织肿块。结论 :胃癌患者应常规行低张螺旋CT检查 ,与其他检查互为补充 ,提供完整的资料 ,有助于临床制订合理的治疗方案更多还原

【Abstract】 Objective: To evaluate the diagnostic value of spiral CT scan with hypotonicity for gastric cancer. Methods: 47 patients with gastric cancer pathologically proven were examined with spiral CT.All the patients received an intramuscular injection of 654 2 (10～20 mg) at ten minute before scanning, followed by drinking 800～1 200 ml of water or 1.5%～2.0% of meglumine diatrnoated. All the patients had plain spiral CT scan and 39 of them had the injection and enhancing CT scan. Results: The location, shape, size, and infiltrative scope of the neoplasms were clearly demonstrated and the metastases to the local lymphonoduli were discovered. The image of gastric cancer characterized as thickened and hardened gastric wall, soft tissue mass, and reduction of gastric volume. Conclusion: The patients with gastric cancer should be examined with spiral CT with hypotonicity in addition to other examinations, which can offer complete data to clinician.更多还原
