摘　　要：目的:探讨320排CT及其后处理图像对食管闭锁合并气管-食管瘘(CEA-TEF)的诊断价值。方法:对怀疑CEA-TEF的9例患儿行320排动态容积CT扫描并进行图像后处理,重组方法包括多平面重组(MPR)、曲面重组(CPR)、最小密度投影(MinIP)、容积再现(VR)和仿真内窥镜(VE),由一位有经验的影像操作技师和一位诊断医师同时观察图像并根据疾病诊断需要进行图像后处理及相关测量。结果:9例中CEA-TEFⅢ型8例(Ⅲa型7例,Ⅲ型b1例),Ⅰ型1例。伴有心血管发育畸形及肛门闭锁各1例。结论:320排动态容积CT及其后处理图像可以准确、无创的对EATEF进行诊断、分型,对寻找瘘口位置、评价肺部情况及观察有无伴随畸形均有重要作用。Objective：To explore the value of 320 row CT and the post-processing images in the diagnosis of esopha- geal atresia combind with tracheal-esophageal fistula （CEA-TEF）. Methods： Nine suspectd cases of CEA-TEF underwent 320 row CT scanning. Post-processing methods included MPR,CPR, MinIP, VR and VE. An experienced technician and a diagnosis physician were responsible for analyzing the images, and according to the need of the diagnosis, making the image post-processing and related measurements. Results：In the 9 children,there was CEA-TEF Type III in 8 cases and Type I in one case. There was cardiovascular malformations in one of them and imperforate anus in another. Conclusion： 320 row CT imaging and post processing images can be accurate and non-invasive methods for the diagnosis of CEA-TEF,as well as its classification, fistula location, evaluation of the lung, and whether with other abnormalities.
