摘　　要：目的观察胃肠道间质瘤(GIST)的多层螺旋CT(MSCT)表现,分析其诊断价值。方法选取我院收治的胃肠道间质瘤且术前行多层螺旋CT的47例患者为研究对象,回顾性分析所有患者多层螺旋CT扫描结果,分析其诊断价值。结果 47例间质瘤中病理诊断良性11例,潜在恶性9例,恶性27例。经统计分析,多层螺旋CT扫描胃肠道间质瘤的形态、大小、边界、密度、强化等指标与其良恶性具有相关性,差异有统计学意义(P<0.05)。结论多层螺旋CT能通过多方位重建(MPR)更清晰显示胃肠道间质瘤病灶的各项特征,有助于判断其良恶性,为诊治及判断预后提供依据。Objective To observe the multilayer spiral CT(MSCT) manifestations of gastrointestinal stromal tumor(GIST) and to analyse its diagnostic value.Methods 47 cases of patients with gastrointestinal stromal tumor and did preoperative MSCTexaminewere selected as the research object,all scan results and its diagnostic valuewere retrospectively analyzed.Results In 47 cases of mesenchymal tumor,11 cases of patients were benign pathological diagnosis,9 cases of patients were malignant potential,27 cases of patients were malignant.Bythe multilayer spiral CT,gastrointestinal stromal tumor form,size,boundary,density and strengthen were relevance with the benign and malignancy,the difference were statistically significant(P<0.05).Conclusion MSCT can clearly display gastrointestinal stromal tumor lesion each characteristicthrough the multi-dimensional reconstruction(MPR),which help to judge its benign and malignancy,and provide basis for the diagnosis,treatment and prognosis.
