摘要
目的:分析胃肠间质瘤的16排螺旋CT表现,探讨其诊断价值。方法:对我院2008年5月～2010年12月经手术病理和免疫组化证实的13例胃肠间质瘤的CT表现进行回顾性分析。结果:13例胃肠间质瘤均为单发,发病年龄37～79岁,平均年龄55岁。良性5例、不确定性3例、恶性5例,其中,病灶位于胃8例,小肠5例。最大径>5cm者,CT表现为形态多不规则,呈外突性或伴浸润性生长,可见囊变坏死,明显不均匀强化,多为高度危险性。最大径<5cm者,形态多规则,边界清楚,呈膨胀性生长,密度均匀,强化均匀,多为中度及以下危险性。结论:CT检查有助于胃肠间质瘤的准确定位,以及观察肿瘤大小、密度、强化特点、形态与周围组织结构的关系。
Objective：To analysis the medical imaging of gastrointestinal stromal tumor with the 16-row spiral CT, to discuss the diagnosis value.Methods：The clinical data of 13 patients for gastrointestinal stromal tumor from 2008 to 2010 which had been proved by Pathological were analyzed retrospectively.Results：13 patients for gastrointestinal stromal tumor were singles,Seizures age is from 37 to 79,average age is 55 years old.Among these cases,5 were benign ttunors,5 were malignant tumors,3 were uncertain.8 cases originated from the Stomach,5 cases originated from the small intestines.The tumors had Irregular shape,convex or infiltration,necrotic,Significantly improved asymmetrically, these above are highly dangerous;Diameter of biggest which was less than 5cm,had ruler shape, even density, Significantly improved,these above were moderate dangerous.Conclusion：16-row spiral CT is helpful for the accurately orientation of the gastrointestinal stromal tumor, to observe the tumor sizes,density, Whether strengthening,the shape,and the relationship with surrondings.
