目的：：探讨胃肠间质瘤MSCT表现及与病理间的关系。方法：收集经病理确诊的胃肠间质瘤23例，对其临床资料及MSCT表现进行回顾性分析。结果：肿瘤位于胃13例，十二指肠1例，小肠5例，食管1例，胃肠道外3例。腔外型5例，壁间型3例，腔内型12例。肿瘤的密度及强化方式与病灶的大小有关，病灶较大者密度更趋于不均匀；肿瘤静脉期强化程度高于动脉期。按照NIH危险度分级标准：极低度1例，低度10例，中度5例，高度7例。结论：MSCT可准确显示胃肠间质瘤的位置、形态及大小，可以初步评估肿瘤的恶性危险度。

Objective:To explore the relationship between MSCT performance of the stromal tumors and gastrointestinal pathology. Methods:A retrospective analysis was performed on the pathological diagnosis,clinical data and MSCT performance in 23 cases of gastrointestinal stromal tumors. Results:There were 13 cases of gastric tumor and 1 case of duodenal tumor,5 cases of small intestine tumor, 1 case of esophagus tumour; and parenteral 3 cases. Outside cavity 5 cases, intramural type 3 cases, intracavity 12 cases were founded. Tumor density and enhancement pattern were related to the size of the lesion,the larger lesions tended to be more uneven. The degree of enhancement of tumor in venous phase was higher than that in arterial phase. Risk classification on NIH criteria:the lowest degree 1 case, low 10 cases, moderate 5 cases, the height 7 cases were founded. Conclusion:MSCT can accurately show the location,shape and size of GIST,and can initially assess the risk of malignant tumors.
