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
Objective: To explore the CT diagnosis of gastric cancer and its value in clinical diagnosis and treatment. Methods: Thirty patients with gastric cancer confirmed by gastroscopy and biopsy were collected and CT scans were performed. Of these, 27 were operated. Gastric contrast agents use 1.5% diatrizoate or water. Twenty-one patients received intramuscular injection of 6 5 4- 2 10 to 20 mg 10 min before the examination. Thirty patients underwent plain CT scans, of which 12 cases were infused with 60% diatrizoate 80 ml via bolus injection. RESULTS: The CT findings of gastric cancer were thickening of the stomach wall and soft tissue shadows in the lesion area. When combined ulcers appeared, thickening of the stomach wall and intraluminal haemorrhoids in the mass. CT can simultaneously detect the invasion and distant metastasis of gastric cancer. Conclusion: CT can be used as a diagnostic method for gastric cancer and has its unique advantages. The purpose of this stage of CT examination of gastric cancer should be pre-treatment assessment and guide clinical development of a reasonable treatment plan
