Serial images of the swallowing motions of 10 healthy volunteers were taken using the Turbo-fast low angle shot (FLASH) magnetic resonance (MR) imaging sequence, while the subject swallowed an oral contrast agent containing ferric ammonium citrate. In all cases, the flow of the contrast agent and the motion of the organs in the oral cavity and the pharynx during swallowing could be observed. High-speed MR imaging combined with an oral positive contrast agent has the potential to evaluate accurately swallowing motion.
使用快速低角度激发（FLASH）磁共振（MR）成像序列，对10名健康志愿者吞咽动作进行连续图像拍摄，同时让受试者吞咽含有柠檬酸铁铵的口服造影剂。在所有情况下，均可观察到吞咽过程中造影剂的流动以及口腔和咽部器官的运动。高速MR成像结合口服阳性造影剂有潜力准确评估吞咽动作。
