摘　　要：目的:探讨胃肠道间质瘤的病理学表现及影像学特征表现,提高间质瘤的影像学认识及诊断准确率。方法:回顾性分析我院2015年12月至2016年8月收治的60例胃肠道间质瘤患者的病理表现及影像学特征,并相互对照分析。结果:60例胃肠道间质瘤患者中发生于食管1例,贲门胃体连接部2例,胃41例,十二指肠5例,小肠11例。术后病理显示良性11例,恶性49例。所有患者经CT检查后,根据灶形态、边界、密度及强化形式等分为低危组和高危组,其中25例为低危组,35例为高危组,其差异有统计学意义(P<0.05)。结论:胃肠间质瘤的CT表现具有一定特征,根据灶形态、边界、密度及强化形式等分为低危组和高危组能为临床合理诊治提供重要的参考信息。To investigate the pathological features and imaging features of gastrointestinal stromal tumors, and improving its diagnostic accuracy. Methods： The pathological features and imaging characteris- tics of 60 cases of gastrointestinal stromal tumors in our hospital fromDecember 2015 to August 2016 were analyzed retrospectively, and mutual control analysis. Results： 1 case of esophagus and cardia gastric body connection department in 2 cases, 41 cases of stomach and duodenum in 5 cases, small intestine in 11 cases. Postoperative pathology showed 11 cases of benign and 49 malignant cases. After CT scanning, all patients were divided into low risk group and high risk group according to the shape, boundary, density and enhancement pattern of the lesion. Among them, 25 cases were low risk group, 35 cases were high risk group, the difference was statistically significant （ P 〈 0. 05 ）. Conclusion： The CT features of gastrointestinal stromal tumors are characteristic. According to the shape, boundary, density and enhancement pattern of the lesion, it can be divided into low risk group and high risk group, which can provide important reference information for clinical diagnosis and treatment.
