Eighteen patients with congenital aortic arch anomalies were evaluated by ECG-gated MR imaging. Transverse images encompassing the heart and thoracic aorta were available in all patients; sagittal or coronal studies were available in 12 patients. Visualization of the aortic arch, its orientation, and the origin and course of the arch vessels was assessed. Associated intracardiac abnormalities were noted, and the effect of aberrant vessels on the trachea or esophagus was determined. Thirteen patients had a right aortic arch. Mirror-image branching was found in 10 cases, and an aberrant left subclavian artery was found in three of these. Three patients had a left aortic arch with aberrant right subclavian artery, and two patients had a double arch. Tracheal compression caused by vascular rings was found in two patients with respiratory symptoms. Corroborating studies (angiography, surgery, CT, and autopsy) in 16 patients confirmed the MR diagnoses in all but one. We conclude that MR could substitute for other techniques as an effective, noninvasive method for the evaluation of congenital aortic arch anomalies.
对18例先天性主动脉弓异常患者进行了心电图门控磁共振成像评估。所有患者均获得了包含心脏和胸主动脉的横向图像；12例患者获得了矢状面或冠状面图像。评估主动脉弓的可视化情况、其方向以及弓血管的起源和走行。记录相关的心内异常情况，并确定异常血管对气管或食管的影响。13例患者为右位主动脉弓。10例发现镜像分支，其中3例发现迷走左锁骨下动脉。3例患者为左位主动脉弓伴迷走右锁骨下动脉，2例患者为双主动脉弓。2例有呼吸道症状的患者发现血管环导致气管受压。16例患者的对照研究（血管造影、手术、CT和尸检）证实除1例之外所有患者的磁共振诊断结果。我们得出结论，磁共振成像可以替代其他技术，作为评估先天性主动脉弓异常的一种有效、无创的方法。
