| 摘 要： | 目的探讨胃肠道间质瘤（gastrointestinal stromal tumors，GIST）影像学表现。方法回顾性分析26例经手术病理证实的GIST临床资料和影像特点。结果26例GIST中内生性生长者4例，外生性生长者19例，腔内外生长者3例。胃肠钡餐检查呈充盈缺损区或弧形压迹，周围黏膜皱襞可变直、牵拉、中断、消失，蠕动减弱。CT平扫呈均匀或不均匀的软组织肿块，其内可出现坏死、囊性变及钙化。增强扫描病灶有不同程度强化，静脉期病变强化程度高于动脉期。超声检查见实性、囊实性占位性病变，肿瘤多呈中等、低回声。结论GIST影像学表现有一些特征性，对诊断有价值。

| Abstract: | Objective To investigate the imaging features of gastrointestinal stromal tumors.Methods The clinical and imaging data of 22 patients with gastrointestinal stromal tumors(GIST)proven pathologically were retrospectively analyzed.Results Endophytic masses were displayed in 4 patients,exophytic masses in 19 patients,and exo-and endophytic masses in 3 patients.The images from the gastrointestinal radiography displayed the filling defect mass and the local mucosal fold that was pressed,pushed or even destroyed.T... |
