目的探讨消化道造影与螺旋CT 用于诊断胃部肿瘤的临床价值。方法 以 我院放射科收治的31例经病理确诊的胃部 肿瘤患者为研究对象，根据其临床资料进 行回顾性分析和总结，分别对其进行消化 道造影检查和螺旋CT检查，以病理诊断结 果为依据，对比分析两种诊断方式的检查 结果。结果 消化道造影诊断阳性28例， 符合率为90.3%；螺旋CT诊断阳性29例， 符合率为93.5%，两者诊断符合率相比， 无统计学意义；消化道造影的敏感性为 92.5%，特异性为67.3%，螺旋CT敏感性为 95.2%，特异性为80.2%，两者相比，差异 无显著意义(P＞0.05)。结论 消化道造影 与螺旋CT在胃部肿瘤的诊断中均具有较高 的应用价值，其诊断准确率高，两者无显 著差异，值得在临床广泛推广和应用。

Objective To explore clinical value of digestive tract radiography and spiral CT for diagnosis of gastric cancer. Methods Thirty one gastric cancer patients admitted by the Radiology Department of the Hospital via pathologically definitive diagnosis were selected as research subjects, who were retrospectively analyzed and summarized according to clinical data, digestive tract radiography examination and spiral CT examination were respectively conducted , and examination findings of two diagnostic approaches were compared and analyzed based on results of pathological diagnosis. Results Digestive tract radiography results of 28 patients were diagnosed to be positive with coincidence rate at 90.3%. Spiral CT results of 29 patients were diagnosed to be positive, and the coincidence rate was 93.5%, and there was no statistical significance when two coincidence rates of diagnosis were compared. The sensitivity and specificity of digestive tract radiography hit 92.5% and 67.3% respectively, while such indexes of spiral CT hit 95.2% and 80.2% respectively, there was no outstanding significance in differences of such two indexed in two groups (P>0.05). Conclusion Digestive tract radiography and spiral CT delivers high value of application in the diagnosis of gastric cancer, the diagnosis accuracy is high, and there is no significant difference, being worthy of application and spread clinically.
