目的 :研究CT检查在胃癌诊疗中的价值。方法 :对 12 6例胃癌患者进行了术前低张水充盈CT动态扫描 ,并和手术标本、术后病理检查对照研究。结果 :胃癌术前CT检出率 10 0 % ,分期准确率 6 1 9% ,胃癌根治性手术切除术前CT阳性预测值 91 6 % ,阴性预测值 71 0 %。结论 :对胃癌患者术前进行动态CT检查是必要的 ,在范围及深度上可弥补胃镜的不足 ,有助于胃癌的诊断与治疗方案的确定
Objective: To study the value of CT in diagnosis and treatment of gastric cancer. Methods: A total of 126 cases of gastric cancer patients underwent preoperative hypotonic water filling CT dynamic scanning, and surgical specimens, postoperative pathological examination control study. Results: The preoperative CT detection rate of gastric cancer was 100% and the accuracy of staging was 61.9%. The preoperative CT positive predictive value was 91.6% and the negative predictive value was 71.0% before radical resection of gastric cancer. Conclusion: Preoperative dynamic CT examination of gastric cancer patients is necessary in the scope and depth to make up for the lack of gastroscope, contribute to the diagnosis of gastric cancer and treatment programs to determine
