【摘要】 目的 :探讨胃癌的 CT诊断征象及在临床诊治中的价值。方法 :收集 30例经胃镜、活检病理证实的胃癌病例 CT扫描 ,其中 2 7例手术。胃对比剂用 1.5 %泛影葡胺或水。 2 1例于检查前 10 min肌注 6 5 4- 2 10～ 2 0 mg。 30例 CT平扫 ,其中 12例经肘静脉团注法注入 6 0 %泛影葡胺 80 ml增强。结果 :胃癌 CT表现为病变区胃壁增厚、软组织块影 ,合并溃疡时表现为增厚胃壁及肿块内的腔内龛影。CT可以同时发现胃癌的邻近侵犯及远处转移。结论 :CT可作为胃癌诊断方法之一 ,并有其独特的优势。胃癌 CT检查现阶段的目的应为疗前评估 ,指导临床制定出合理的治疗方案更多还原

【Abstract】 Objective:To evaluate the characteristic signs and value of CT in the diagnosis of gastric carcinoma.Methods:30 patients with pathologically proven gastric carcinoma were examined by CT scan.The diagnosis was based on gastroscopy.Of 30 patients,27 had surgical results.Meglumine diatrizoate(1.5%)or water were selected as gastric contrast-medium.At 10 minutes before the procedure of CT, 21 patients received an intramuscular administration of 654-2(10～20 mg).All the patients had no-enchanced CT scan,among them 12 patients had bolus injection enchanced CT scan.Results:The basic CT signs of gastric carcinoma demonstrated thickened gastric wall and soft tissue mass.Irregular intracavitary niches were noticed when combined with ulcer.Gastric wall rigidity and deformation were also the CT features of gastric carcinoma.Direct infiltration and distal metastasis of gastric carcinoma were observed by CT.Conclusion:CT is an effective method for examining gastric carcinoma.It has important value in staging of the gastric carcinoma and giving rational therapeutic plan before treatment.更多还原
