摘要
目的探讨胃肠道间质瘤(GIST)的低张气钡双重造影和螺旋CT影像特点。方法回顾性分析25例经病理和手术证实的胃肠道间质瘤的影像资料。结果胃肠道低张气钡双重造影表现为腔内充盈缺损,龛影,局部黏膜展平消失,瘤周黏膜推移,小肠肠腔狭窄和胃肠道受压移位。CT表现为腔内或腔外肿块,肿块内可见液化、坏死、囊变,病变区中度强化或不均匀强化;管壁局限性增厚和转移病变。结论胃肠道低张气钡双重造影对黏膜及黏膜下病变和管壁功能性改变具有优势,而CT能明确显示肿瘤的的形态大小、内部结构及其与周围组织脏器的关系,能提供更多的胃肠道腔外影像信息。
Objective To investigate the imaging features of spiral CT and hypotonic double contrast radiography of gastrointestinal tract in gastrointestinal stromal tumors （GIST）. Methods Imaging informations of 25 patients with GISTs confirmed by surgery and pathology were retrospectively analyzed. Results The imaging features of hypotonic double contrast radiography of gastrointestinal tract included intraluminal filling defect, niche, local mueosa flattened, gastrointestinal tract displaced. The imaging features of CT included soft tissue mass inside lumen or outside, necrosis and cystiform degeneration within the mass, the solid portion of tumors moderately en- hanced. Conclusion The hypotonic double contrast radiography of gastrointestinal tract has the advantage showing lesion of mucosa and submucosa, functional abnormalities. CT may provide more information of tumors outside lu- men, such as shape and size, internal structure, relationship with the surrounding tissue.
