Transposition of Dynamic MRI Data From Healthy Subjects to an in Vitro Swallowing Simulator

"The examination recording a total of 9 sequences of less than 30 seconds will be performed, in transverse section (passing through the epiglottis), frontal section, in the plane of the posterior pharyngeal wall, and in median sagittal section.~Each bolus of 20 ml will be administered in full, in one go, using a syringe. It is kept in the mouth for a few seconds and swallowed on demand.~The semi-liquid bolus of 20 ml comes from the mixture of 198 ml of pineapple juice to 10 gr of Nutilis Powder (NUTRICIA), food thickener containing neither gluten, nor lactose.~Ingredients: Dextrin-maltose, thickeners (modified starch (corn), tara gum, xanthan gum, guar gum).~* 3 sequences with no food~* 3 sequences with ingestion of a liquid bolus of 20 ml (pineapple juice) mouth closed~* 3 sequences with ingestion of a semi-liquid bolus of 20 ml (pineapple juice + Nutilis Powder) mouth closed"
