| 摘 要： | 目的 探讨胃肠道间质瘤(GIST)的CT表现,以提高对GIST的诊断水平.方法 搜集经手术和病理证实的胃肠道间质瘤32例,回顾性分析其CT和病理表现.所有病例均行CT平扫及增强扫描.结果 32例肿瘤均为单发,位于胃部17例,空肠和回肠7例,结肠及直肠3例,食管1例,十二指肠和肠系膜各2例.良性9例,恶性23例.CT表现为黏膜下富血供性肿块,肿瘤倾向于腔外生长,可有囊变、坏死及钙化.双期增强扫描见静脉期较动脉期强化显著.结论 CT是GIST的主要影像学检查方法 ,CT表现有一定的特征性,对胃肠道间质瘤的定位和定性判断以及鉴别诊断有重要价值,但定性诊断需依赖免疫组化和电镜检查.
