摘　　要：目的:探讨MSCT及重组技术对消化道刺状异物的诊断价值。方法:回顾性分析经手术或消化道内镜证实的的30例消化道刺状异物患者的临床和影像学资料。食管异物患者仅行食管MSCT平扫,胃肠异物患者均行腹部动、静脉双期增强扫描。扫描图像行0.625mm薄层重组及多平面重组。结果:30例消化道刺状异物患者中,26例为食管异物,1例为胃异物,3例为十二指肠和空肠异物。28例异物为鱼刺,1例为牙签,1例为胆道引流管移位。结论:MSCT结合重组技术有助于消化道刺状异物及相应并发症的诊断,能为临床治疗方案提供指导。Objective： To explore the value of MSCT and postprocessing techniques in diagnosis of digestive tract spinous foreign bodies. Methods： The clinical and imaging data of 30 patients with digestive tract foreign bodies confirmed by surgery or endoscopy were retrospectively analyzed. CT plain scans were performed for the patients suspected with esopha geal foreign bodies. Dualphase contrast enhancement CT scans were performed for the patients suspected with gastrointes tinal foreign bodies. All images were transmitted to AW4.3 station for reconstruction with 0. 625mm thickness and multi planar reformation. Results： From all the 30 patients, 26 patients had esophageal foreign bodies, one patient had gastral for eign body,3 patients had duodenal and jejunal foreign bodies. 27 foreign bodies were fish bones,one was toothpick,and one was migrated drainage tube from bile duct. Conclusion： Using MSCT and postprocessing techniques not only can help the diagnosis of gastrointestinal foreign bodies, but also can evaluate complications of the foreign bodies and provide guidance for clinical treatment.
