The aortic arch can be clearly demonstrated in neonatal chest radiographs by use of a high kilovoltage-filtered film with air-gap magnification. This allows identification of the presence of right aortic arch in patients with esophageal atresia and tracheoesophageal fistula; awareness of this anomaly may influence choice of surgical approach.
通过使用高千伏滤线片并结合空气间隙放大技术，可在新生儿胸部X线片中清晰显示主动脉弓。这有助于识别食管闭锁和气管食管瘘患者中右位主动脉弓的存在；认识到这种异常情况可能会影响手术入路的选择。
