摘　　要：目的探讨胃肠道间质瘤（GIST）的CT征象及其诊断价值。方法回顾性分析经手术病理证实的10例胃肠道间质瘤患者的CT征象。结果肿瘤位于胃部6例，小肠3例，肠系膜1例，CT定位诊断符合率80％（8／10）。免疫组化提示CD117、CD34多为弥漫阳性。肿块多表现为圆形或类圆形，可发生囊变或坏死，少数可见出血。肿瘤实质部分中到明显强化，静脉期进一步强化。结论胃肠道间质瘤（GIST）的CT表现具有一定特点，能准确显示肿瘤的部位、形态、大小，对肿瘤的诊断及良恶性鉴别有重要价值。Objective To study CT features of gastrointestinal stromal tumors （GIST）and its diagnostic value . Methods The CT features in 10cases with GIST proved by surgery and pathology were retrospectively analysed. Results 6 cases tumors originated from the stomach, 3 cases tumors originated from the small bowel, 1 cases tumors originated from the mesentery,The accurate rate in localization of GIST with CT was 80%. Immunohistoehemistry test pointed out CD117 （＋）, CD34（＋ ）.The tumors were mainly round or oval in shape, most tumors showed cystic degeneration or necrosis, a part of cases showed haemorrhage, The solid parts of tumors enhanced moderately to markedly and further enhancement during venous phase. Conclusion CT sign in GIST has certain characteristic, CT can detect the location, shape and size of tumors, and it is of impor/ant value in the diagnosis and differentiation the benign from malignant tumors.
