To introduce a new high-speed, continuous, T2-weighted magnetic resonance imaging (MRI) technique for the evaluation of swallowing by visualizing the flow of saline.
In 20 healthy participants, high-speed (10 frames per second), continuous MRI of the pharynx and larynx was performed during administration of 5 mL of saline. The extent to which fluid flow and swallowing (including flow to the esophagus or trachea) could be visualized was determined for all 20 participants.
Solution flow was visualized, and swallowing events, including the direction of flow to the esophagus, could be visualized with high-speed, continuous MRI for all 20 participants.
This initial study suggests that the visualization of saline flow using our method may facilitate functional evaluation of swallowing without side effects.
介绍一种新的高速、连续的T2加权磁共振成像（MRI）技术，通过可视化盐水流动来评估吞咽功能。
对20名健康参与者在给予5毫升盐水期间进行咽部和喉部的高速（每秒10帧）连续MRI检查。确定了所有20名参与者中液体流动和吞咽（包括流向食管或气管）的可视化程度。
所有20名参与者均可通过高速、连续MRI观察到溶液流动以及吞咽事件，包括流向食管的方向。
这项初步研究表明，使用我们的方法可视化盐水流动可能有助于在无副作用的情况下对吞咽功能进行功能评估。
