Tracheobronchial anomalies are common in congenital heart disease (CHD), including tracheobronchial stenosis, tracheal bronchus, cardiac bronchus, and bronchial isomerism, which can cause varying degrees of respiratory illness. It is necessary to assess tracheobronchial anomalies and make a preoperative airway evaluation. Multi-slice computed tomography (MSCT) and cardiac magnetic resonance imaging (MRI) are the most effective noninvasive modalities for the diagnosis of CHD and the associated tracheobronchial anomalies. However, MSCT remains an ionizing procedure despite using low dose protocols. The aim of this study was to evaluate diagnostic accuracy of tracheobronchial anomalies in patients with CHD using three-dimensional turbo field echo(3D-TFE) magnetic resonance imaging sequence for preoperative airway evaluation. The results indicated that 3D-TFE provided better image quality as compared to that of 3D-balanced turbo field echo (3D-bTFE), and it can clearly demonstrated the tracheobronchial tree and tracheobronchial anomalies in CHD. This study confirms the clinical value of 3D-TFE in diagnosing tracheobronchial anomalies and supply helpful tracheobronchial information for preoperative strategies and postoperative follow-up.
气管支气管畸形在先天性心脏病（CHD）中很常见，包括气管支气管狭窄、气管支气管、心脏支气管和支气管异构，可导致不同程度的呼吸系统疾病。评估气管支气管畸形并进行术前气道评估很有必要。多层螺旋计算机断层扫描（MSCT）和心脏磁共振成像（MRI）是诊断CHD及相关气管支气管畸形最有效的无创检查方法。然而，尽管使用了低剂量方案，MSCT仍是一种电离程序。本研究的目的是使用三维快速场回波（3D-TFE）磁共振成像序列评估CHD患者气管支气管畸形的诊断准确性，用于术前气道评估。结果表明，与三维平衡快速场回波（3D-bTFE）相比，3D-TFE提供了更好的图像质量，并且它可以清晰地显示CHD中的气管支气管树和气管支气管畸形。本研究证实了3D-TFE在诊断气管支气管畸形方面的临床价值，并为术前策略和术后随访提供了有用的气管支气管信息。
