目的 通过与病理对照，分析胃 肠道间质瘤多层螺旋CT(MSCT)表现及其诊 断价值。方法 对我院2013年1月-2015年6 月经手术病例证实的48例胃肠道间质瘤患 者的MSCT及病理资料进行回顾性分析。结 果 病理诊断良性间质瘤12例，恶性或潜 在恶性间质瘤36例。良性间质瘤与恶性 或潜在恶性间质瘤在病灶大小、部位、 形态、边界、密度、强化及周边器官侵 犯MSCT表现上比较差异有统计学意义(P ＜0.05)。结论 MSCT对胃肠道间质瘤病灶 大小、部位、内部结构及与周边器官关系 能有效显示，且对肿瘤良恶性判断有一定 的价值。

Objective To analyze the findings and diagnostic value of multi-slice spiral CT (MSCT) of gastrointestinal stromal tumor by contrasting with pathology. Methods The MSCT and pathological data of 48 patients with gastrointestinal stromal tumors confirmed by operation and pathology in our hospital from January 2013 to June 2015 were retrospectively analyzed. Results 12 cases of benign stromal tumors and 36 cases of malignant or potential malignant stromal tumors were diagnosed by pathology. There were statistically significant differences in MSCT sindings of the size, location, shape, border, density, enhancement and surrounding organ invasion of lesions between benign stromal tumors and malignant or potential malignant tumors (P<0.05). Conclusion MSCT can effectively display the size, location, internal structure and relationship with the surrounding organs of the gastrointestinal stromal tumors and it has certain value in the judgement of benign and malignant tumors.
