Velopharyngeal Insufficiency (VPI) is a condition in which the velopharynx does not properly close during speech production. The condition can be improved with surgery after evaluation with videofluoroscopy and/or nasendoscopy. MRI may provide a non-invasive and non-radiative alternative. We present a protocol for acquiring two images per second of the velopharyngeal anatomy during speech production and a method implemented on the scanner for automatically generating an mpeg movie from the image series along with a synchronized audio recording using an optical microphone. The movie is available for review on the scanner immediately after imaging.
