| 目的 探讨MSCT和MR三维快速场回波（3D-TFE）序列诊断儿童双侧气管性支气管的价值。方法 回顾性分析14例双侧气管性支气管患儿的胸部MSCT或MRI资料。对10例MSCT图像采用最小密度投影技术进行气道重建；对4例采用MR 3D-TFE序列扫描获得气道图像，并以最大密度投影重建气道。根据MSCT或MRI将患儿分为标准型（双侧气管性支气管均从气管隆嵴上方发出）、临界型（双侧气管性支气管均从气管隆嵴起始部发出）和混合型（双侧气管性支气管从不同位置发出），分析图像特点及合并心脏畸形。结果 MSCT和MR 3D-TFE序列均可清晰显示双侧气管性支气管。14例中，标准型8例（8/14，57.14%），临界型5例（5/14，35.71%），混合型1例（1/14，7.14%）。14例（14/14，100%）患儿均合并无脾综合征。较高发的合并心脏畸形包括共同房室通道（12/14，85.71%）、肺动脉狭窄（11/14，78.57%）和永存左上腔静脉（11/14，78.57%）。结论 MSCT和MR 3D-TFE序列对双侧气管性支气管有良好诊断价值。 |

| Objective To observe clinical value of MSCT and MR three-dimensional turbo field echo (3D-TFE) in diagnosis of children bilateral tracheal bronchi. Methods Data of 14 cases of children bilateral tracheal bronchi examined with MSCT or MR were retrospectively reviewed. Minimum intensity projection was used to reconstruct the airway in 10 children who underwent MSCT scanning, while maximum intensity projection was used to appear the airway in 4 children underwent MR 3D-TFE. According to MSCT or MRI, bilateral tracheal bronchi were divided into standard type (bilateral tracheal bronchi originated from the upper part of tracheal eminence), critical type (bilateral tracheal bronchi originated from the beginning of tracheal eminence) or mixed type (bilateral tracheal bronchi originated from different locations). The characteristics and other heart anomalies of these children were recorded. Results Bilateral tracheal bronchi were showed clearly on both MSCT and MR 3D-TFE images. Among 14 cases, 8 cases (8/14, 57.14%) were found with standard type bilateral tracheal bronchi, 5 cases (5/14, 35.71%) were found with borderline type, 1 case (1/14, 7.14%) was found with mixed type bilateral tracheal bronchi. All 14 children (14/14, 100%) were detected with asplenia syndrome. The most common cardiac malformations included common atrioventricular canal (12/14, 85.71%), pulmonary stenosis (11/14, 78.57%) and persistent left superior vena cava (11/14, 78.57%). Conclusion MSCT and MR 3D-TFE sequences have good diagnostic value for assessing bilateral tracheal bronchi. |
