摘　　要：目的探讨胃肠道间质瘤（GIST）的CT征象，评价其诊断价值。方法回顾性分析15例经手术病理证实的GIST的CT表现。结果15例GIST中原发于胃8例，十二指肠1例，空回肠3例，结肠1例，肠系膜来源2例。CT表现为软组织肿块，常伴有囊变、坏死及出血，实质部分强化明显，静脉期强化较动脉期明显。结论CT能够准确显示GIST的部位、形态、大小及强化特点，对于术前定位、定性和肿瘤分级具有重要价值。Objective To investigate the value of multi-slice CT in the diagnosis of gastrointestinal stromal tumor. Method CT image of 15 cases of GIST confirmed by surgical pathology were analyzed retrospectively. Resuits The tumors originated from the stomach（ n = 8） ,duodenum（ n = 1 ） ,jejunum and ileum（ n =3） ,colon（ n = 1 ）, mesentery（n = 2）. The main display of CT were hemorrhage,necrosis and cystic change within the tumor. The enhancement of parenchyma was clear. The enhancement of venous phase was more clear than that of arterial phase. Conclusion MSCT is a valuable examination for GIST. MSCT can precisely display the location,shape, size and enhancement of GIST. MSCT can be worth the locating,qualitative and staging diagnosis.
