Oesophageal atresia (OA) is an important congenital malformation in which prompt diagnosis and appropriate management can significantly improve outcome. The surgical approach to repair of OA and associated tracheo-oesophageal fistulae (TOF) depends upon correct evaluation of the tracheobronchial tree. Three-dimensional imaging of the tracheobronchial tree using CT data to produce shaded surface displays and virtual bronchoscopy has been reported in paediatric and neonatal patients with OA and TOF and is described as accurate and helpful, non-invasively facilitating the appreciation of complex anatomy prior to surgery. We describe the technique of reconstructing 3D volume-reformatted 'transparency' images using insufflated air as a negative contrast medium. This technique is fast, accurate and produces high-quality images that are easy to reproduce.
食管闭锁（OA）是一种重要的先天性畸形，及时诊断和恰当处理可显著改善预后。修复OA及相关气管食管瘘（TOF）的手术方法取决于对气管支气管树的正确评估。利用CT数据对气管支气管树进行三维成像以生成表面阴影显示和虚拟支气管镜检查，已在患有OA和TOF的儿科及新生儿患者中得到报道，被描述为准确且有帮助，可在手术前以非侵入性方式辅助了解复杂的解剖结构。我们描述了一种使用注入空气作为阴性对比剂重建三维容积重组“透明”图像的技术。该技术快速、准确，能生成易于再现的高质量图像。
