摘　　要：目的研究胃间质瘤(GST)的CT影像学表现,预测肿瘤的恶性程度。方法研究32例经手术或穿刺活检并经病理证实的GST患者的临床资料及CT表现,分析肿瘤的大小、形态、部位、边界、生长方式、密度、强化程度、坏死囊变及脂肪间隙情况。结果低度危险肿瘤12例,中度危险肿瘤12例,高度危险肿瘤8例。肿瘤的大小、形态、边界、生长方式、密度、强化程度、坏死囊变及脂肪间隙情况与危险度的差异具有统计学意义(P<0.05),而患者的性别、肿瘤的发病部位与危险度之间无统计学差异(P>0.05)。结论 CT对胃间质瘤的诊断及危险度的分级具有重要作用,对临床诊治具有重要价值。Objective To study the gastric stromal tumor （GST） performance of the CT imaging, prediction of malignancy tumor. Materials 32 cases confirmed by operation or biopsy and clinical data and CT findings of pathologically proved GST were analyzed, the tumor size, shape, location, boundary, growth pattern, density, degree of enhancement, necrosis and fat clearance. Results 12 cases of low risk tumor, 12 cases of moderate risk tumor, 8 cases of high tumor. Statistically significant size, shape, boundary, the difference of growth pattern, density, degree of enhancement, necrosis and fat clearance and the risk of cancer （P〈0.05）, but there was no difference between the incidence of and risk sex, tumor patients （P〉0.05）. Conclusion CT plays an important role in the diagnosis and classification of gastric stromal tumor risk degree, has the important value to the clinical diagnosis and treatment.
