OBJECTIVES/HYPOTHESIS: In this article we describe a methodology for obtaining high-quality dynamic magnetic resonance imaging (MRI) sequences of the swallow sequence in healthy volunteers. The study includes comparison to previous work done in our lab using a 1.5 Tesla (T) magnet.
Case series.
Three healthy volunteers underwent turbo-fast low angle shot MRI at 3T while swallowing liquid boluses delivered via intravenous tubing to the oral cavity. Imaging was performed in the sagittal and axial planes.
Imaging provided by this sequence provided high temporal resolution, with the ability to depict deglutition in the axial and sagittal planes. Comparison with imaging at 1.5 T demonstrated benefits in temporal resolution and signal-to-noise. Anatomic information provided differed from comparative videofluoroscopy.
MRI of swallowing using the described technique is reliable and provides a unique evaluation of the swallowing sequence.
目的/假设：在本文中，我们描述了一种从健康志愿者中获取高质量动态磁共振成像（MRI）吞咽序列的方法。该研究包括与我们实验室之前使用 1.5 特斯拉（T）磁体进行的研究的比较。
病例系列。
三名健康志愿者在 3T 时进行涡轮快速低角度 shot MRI，同时通过静脉管将液体团块输送到口腔中进行吞咽。成像在矢状面和轴位进行。
该序列提供的成像具有高时间分辨率，能够在轴位和矢状面描绘吞咽。与 1.5 T 的成像相比，该方法在时间分辨率和信噪比方面具有优势。提供的解剖信息与比较性荧光透视术不同。
使用所描述技术的吞咽 MRI 是可靠的，并提供了吞咽序列的独特评估。
