16层螺旋CT三维重建成像在食源性食管异物诊断中的价值

摘要

目的 探讨16层螺旋CT三维重建成像在诊断食源性食管异物中的价值.方法 回顾20例经食管镜、手术证实的食道异物患者,通过MSCT三维重建:多平面重建(MPR)、最大密度投影(NIP)、容积再现(VR)与X射线平片、食管镜检等,比较其诊断价值.结果 经食管镜或手术证实的20例患者的食管异物为鸡骨、鸭骨、鱼骨片、鱼刺等;16层螺旋CT三维重建成像对异物形态、大小、长度、边缘锐利度能清楚显示,且定位准确.结论 16层螺旋CT三维重建成像异物检出率较X射线平片、食道镜检高,同时可评价食管损伤程度、有无并发症等,全方位展示异物与食道周围组织的关系.%Objective To study three-dimensional reconstruction of 16-lice CT imaging in the diagnosis of esophageal foreign bodies in food-borne value.Methods 20 patients with esophageal foreign bodies proved by esophagoscopy and surgical were examined by three-dimensional reconstruction of MSCT: multi-planar reconstruction (MPR), maximum intensity projection (MIP), volume rendering (VR) and X-ray.Then the diagnostic value were compared. Results The esophageal foreign bodies of 20 patients werechicken bone,duck bone, fish bone slices, fish bone and so on. 16-slice spiral CT three dimensional reconstruction image of the foreign body shape, size, length, edge sharpness can show them clearly and position accurately. Conclusion 16-lice spiral CT three dimensional reconstruction imaging was better than X-ray and esophagoscopy in foreign body detection diagnosis, and it can evaluate the degree of esophageal injury and complications,and display of esophageal foreign body with surrounding organizations.
