On the Physiology of Normal Swallowing as Revealed by Magnetic Resonance Imaging in Real Time
Figure 2
Durations, start times, and end times of distinct swallowing events as determined by real-time MRI (means and quartiles, 10 subjects). LAT: laryngeal ascent, VCT: velo-pharyngeal closure, OOT: oro-velar opening (start time defined as reference), OTT: oro-velar transit, PDT: pharyngeal delay, PTT: pharyngeal transit, GCT: glottal closure, SFT: vallecular and piriform sinus filling, ERT: epiglottic retroflexion, PCT: pharyngeal constriction, EOT: esophageal opening, and LDT: laryngeal descent.
