Research Abstract

Evaluation of swallowing has been made possible by cine-Magnetic resonance(MR)imaging with high time resolution. Therefore, it is necessary to refer to static MR images in conjunction with cine-MR images. The aim of this study was to determine which MR parameters were appropriate for static imaging of the anatomical structures involved in swallowing.
