A prospective study by nuclear magnetic resonance in 7 infants with respiratory disorders and with a barium swallow suggestive of anomalies of the aortic arch was conducted. It allowed the definition of an investigation protocol including sedation, RF coil adapted to infants size, naso-gastric tube placement, thin MR sections. Sequences are T1 weighted with ECG gating in two perpendicular frontal oblique and transverse oblique planes determined on a scout sagittal MR acquisition. Precise determination of the anatomy of the vascular malformation and its relationship with the trachea and esophagus were obtained. After definition of the investigation protocol, MRI was found to be a very effective evaluation technique for aortic arch anomalies. It can be proposed as an alternative to preoperative digital angiography. Its indications remain to be defined in relation to the clinical features and the results of the chest X-ray and barium swallow.
对7例患有呼吸系统疾病且钡餐检查提示主动脉弓异常的婴儿进行了一项核磁共振前瞻性研究。该研究确定了一个检查方案,包括镇静、适合婴儿尺寸的射频线圈、鼻胃管放置、薄层磁共振成像。序列为T1加权成像,在矢状面磁共振定位像上确定的两个相互垂直的额斜位和横斜位平面上进行心电图门控。获得了血管畸形解剖结构及其与气管和食管关系的精确测定结果。在确定检查方案后,发现磁共振成像对于主动脉弓异常是一种非常有效的评估技术。它可被提议作为术前数字血管造影的替代方法。其适应证仍需根据临床特征以及胸部X线和钡餐检查结果来确定。
