摘　　要：目的探讨能谱CT在胃癌术前分期中的应用价值。方法回顾性分析2014年6月-2016年3月我院肿瘤外科收治的经手术病理证实的50例进展期胃癌患者的临床资料,所有病例患者术前均行能谱CT扫描,对所有病例患者CT能谱特征进行回顾性分析,并与病理结果对照,进而探讨能谱CT在胃癌术前分期中的应用价值。结果能谱CT显示50例胃癌患者病变部位贲门部25例,胃底体部18例,胃窦部7例;低、中、高分化腺癌例数分别为31例、18例、1例;组织病理学检查提示胃癌术前T分期中T1、T2、T3、T4期所占百分比数值分别为8.00%、18.00%、52.00%、22.00%。结论能谱CT在胃癌术前分期中有较高的应用价值,对胃癌患者进行较准确的术前分期诊断,为其临床及时、合理治疗提供科学理论依据。Objective To investigate the application value of CT in preoperative staging of gastric cancer. Methods The clinical data of 50 patients with advanced gastric cancer confirmed by operation and pathology who were treated in our hospital during June 2014 - March 2016 were analyzed retrospectively. All patients underwent energy spectrum CT scan and the results were compared with the pathological results to explore the application value of energy spectrum CT in preoperative staging of gastric cancer. Results Energy spectrum CT showed that lesions in 50 cases of gastric cancer patients distributed in cardia in 25 cases, in fundus of stomach in 18 cases and in antrum in 7 cases. The numbers of cases with lowly, moderately and highly differentiated adenocarcinoma were 31, 18 and 1 case, respectively. Histopathological examination showed that the percentages of stage T1, T2, T3 and T4 in preoperative T stage were 8.00%, 18.00%, 52.00% and 22.00%, respectively. Conclusion Energy spectrum CT is of high application value in the preoperative staging of gastric cancer, it can provide a scientific basis for the timely and reasonable treatment of patients with gastric cancer.
