目的：评价MSCT及其后重组图像对食管闭锁合并气管食管瘘疾病（EA-TEF）的诊断。方法：对疑诊EA-TEF的12例患儿行MSCT扫描后进行后处理重组，重组方法包括：多平面重组（MPR）、最小密度投影（MinIP）、容积重组法（VR）、仿真内窥镜法（VE），由两位有经验的影像医生同时观察图像并进行相关测量。结果：12例中包括Ⅲ型11例（Ⅲa型1例，Ⅲb型10例），Ⅳ型1例。6例（50％）伴随6种畸形。结论：MSCT及其后重组图像可以准确、无创的对EA-TEF进行诊断、分型、寻找瘘口位置、同时评价肺部情况及伴随的其它畸形。

Objective: To study the value of multi-slice CT(MSCT) in the diagnosis of esophageal atresia and tracheoesophageal fistula(EA-TEF) in neonate. Methods: Twelve patients suspected to have EA-TEF were examined by MSCT. Multi-planar reformation(MPR), minimum intensity projection(MinIP), volume-rendered image(VR), and virtual endoscope(VE) were reconstructed at workstation. Two experienced radiologists overviewed the images and were related measurements. Results: There were 11 cases of type Ⅲ EA-TEF(including 1 case of type Ⅲa, 10 cases of type Ⅲb) and 1 case of type Ⅳ. Six patients had 6 types of congenital malformations. Conclusions: MSCT and reconstruction images has great value in diagnosing, typing, searching fistula of EA-TEF disease and could evaluate lung condition and related malformations.
