目的：研究CT检查对胃癌诊治的价值。方法：从1995年9月到1996年8月，对53例胃癌患者进行了术前低张水充盈CT动态扫描，并和术后病理检查对照研究。结果：53例对照研究表明，胃癌术前CT检出率100％，胃癌术前CT分期准确率60．3％，胃癌可行根治性手术切除术前CT估价的准确性88．24％，难以根治性手术切除术前CT估价的准确性57．89％。结论：对胃癌患者术前进行动态CT检查是必要的，在范围及深度等定位诊断上可弥补胃镜的不足，有助于胃癌的诊断与治疗。
Objective: To study the value of CT examination in the diagnosis and treatment of gastric cancer. METHODS: From September 1995 to August 1996, 53 cases of gastric cancer patients underwent preoperative CT scan with dynamic CT scans and were compared with postoperative pathological examinations. RESULTS: A total of 53 controlled studies showed that the preoperative CT detection rate of gastric cancer was 100%, the accuracy of preoperative CT staging of gastric cancer was 60.3%, and the accuracy of preoperative CT evaluation of gastric cancer after feasible radical resection was 88.24%, which was difficult to cure. The accuracy of preoperative CT evaluation was 57.89%. Conclusion: It is necessary to carry out dynamic CT examination before operation in patients with gastric cancer. It can make up for the deficiency of gastroscope in the range and depth of diagnosis, which is helpful to the diagnosis and treatment of gastric cancer.
