目的 :探究胃癌的CT表现及诊断价值。方法 :2014年8月-2016年8月,选择医院胃镜检出的162例胃癌患者,同期收治的胃溃疡与癌前病变患者100例,进行CT检查。结果 :CT鉴别诊断胃癌、胃溃疡与癌前病变,敏感度98.77%(160/162),特异度88.00%(88/100),符合率94.66%(248/262);CT分期与病理T分期Kappa=0.428,中度一致性,CT诊断T1、T2、T3、T4准确率差异具有统计学意义(P<0.05)。结论 :CT可鉴别诊断胃癌,还有助于进行病理分期,特别是早期、进展期胃癌鉴别诊断率较高。
Objective: To investigate the CT findings and diagnostic value of gastric cancer. Methods: From August 2014 to August 2016, 162 cases of gastric cancer detected by hospital gastroscopy were selected, 100 cases of gastric ulcer and precancerous lesions were treated at the same period, and CT examination was performed. Results: The sensitivity and specificity of CT in the differential diagnosis of gastric cancer, gastric ulcer and precancerous lesions were 98.77% (160/162) and 88.00% (88/100), respectively. The coincidence rate was 94.66% (248/262) Kappa = 0.428, moderate consistency, CT diagnostic accuracy of T1, T2, T3, T4 difference was statistically significant (P <0.05). Conclusion: CT can differentiate the diagnosis of gastric cancer, but also help the pathological staging, especially in early, advanced gastric cancer higher differential diagnosis.
