摘　　要：目的总结分析胃肠道间质瘤(GIST)的CT表现特征,评价64排螺旋CT对该肿瘤的诊断价值。方法回顾分析12例外科切除术后GIST病例的临床、64排螺旋CT及病理资料。结果本组GIST其中7例(占58.33%)发生在胃,2例(占16.67%)发生在肠系膜;CT显示低度危险性病灶密度均匀,轻中度强化,界面清楚,腔内生长;高度危险性病灶内见液化坏死、囊变、出血、钙化,瘤旁簇状血管及增粗供血动脉,无淋巴结转移。结论 64排螺旋CT对显示GIST内部结构、肿块与胃肠道关系和肿瘤血管情况等具有极高的价值。OBJECTIVE To evaluate the value of VCT diagnosis of GIST by analyzing the CT characteristics of gastrointestinal stromal tumors（GIST）.METHODS Retrospectively analyzed 12 cases of GIST confirmed by pathology.RESULTS GIST often occurred in the stomach（58.33%）,also could occur outside the gut（16.67%）;lesions with low degree of risk had uniform density,moderate intensification,well defined interface,cavity growth;lesions with high degree of risk had the liquefaction necrosis,cystic change,hemorrhage,calcification,tumor blood vessels adjacent to clusters artery,without lymph node metastasis.CONCLUSION VCT has a very high value of diagnosis which can shows the internal structure of GIST,the relationship between tumor and gastrointestinal tract,and blood vessels of tumor.
