目的：探讨胃肠道间质瘤C T 表现以及与肿瘤危险程度的相关性。方法回顾性分析53例经手术病理证实的胃肠道间质瘤C T表现并与肿瘤危险程度分级进行对照。结果极低危险组4例，低度危险组18例，中度危险组17例，高度危险组14例。性别、年龄与肿瘤的危险程度无统计学意义（ P ＞0．05）。肿瘤的大小、边界、密度、强化方式及有无转移灶与肿瘤的危险程度有统计学意义（ P＜0．05），而肿瘤的生长部位、生长方式及与胃肠道是否相通与危险程度无统计学意义（ P ＞0．05）。结论胃肠道间质瘤CT 表现具有一定的特征性，肿瘤的大小、边界、密度、强化方式及有无转移可以判断肿瘤的危险程度，对指导临床治疗及预后评估均有重要意义。

Objective To discuss the relationship between CT features and degrees of mallignancy of gastrointestinal stromal tumors (GIST ) .Methods The 53 cases of GIST comfirmed by pathology were tetrospectively studied and com-pared with different risk of pathologic findings by analyzing the CT features of GIST .Results All 53 cases of GIST in-cluded 4 very low risk ,18 low risk ,14 intermediated risk and 12 high risk cases .Gender and ages among tumor risk de-grees were no statistical significance .Lesion size ,boundary ,density ,strengthening modes ,whether metastases in GIST among different risk groups were statistically different .Growth pattern ,location ,whether intercommunicated with gas-trointestinal tract in GIST among different risk groups were no statistically different .Conclusion CT imaging manifesta-tions of gastrointestinal stromal tumors were found with certain characteristics .Lesion size ,boundary ,density ,strengthe-ning modes ,whether metastases in GIST could judge the degrees of mallignancy ,which can guide the clinical treatment and prognosis assessment .
