Summary

The emergence of turbo-FLASH MR sequences allows us to acquire five 10-mm sections each second and thus to catch images of the soft tissues during function. One can trace the pathway of a liquid between the tongue, the soft palate, the epiglottis and the pharyngeal apparatus and analysis the role of the anatomic structures during swallowing. Restricted to the sagittal plane for the purpose of this preliminary study, this technique can be extended to the other planes to provide a three-dimensional analysis of oropharyngeal function or dysfunction.

Résumé

L'apparition des séquences IRM “turbo-FLASH” permet la réalisation de coupes rapides des tissus mous en mouvement. Il est ainsi possible de suivre chronologiquement la progression d'un liquide entre la langue, le palais mou, l'épiglotte et le pharynx lors d'une déglutition et d'observer le jeu des structures anatomiques. Cette technique, volontairement limitée au plan sagittal dans le cadre de cette étude préliminaire, peut être étendue aux autres plans et fournir ainsi une représentation tridimensionnelle des fonctions ou dysfonctions oro-pharyngées.
