Acoustic-integrated dynamic MR imaging for a patient with obstructive sleep apnea

Magn Reson Imaging. 2015 Dec;33(10):1350-1352. doi: 10.1016/j.mri.2015.08.004. Epub 2015 Aug 13.

Abstract

Obstructive sleep apnea syndrome (OSAS) is caused by multi-level upper airway obstruction. Anatomic changes at the sites of obstruction may modify the physical or acoustic properties of snores. The surgical success of OSA depends upon precise localization of obstructed levels. We present a case of OSAS who received simultaneous dynamic MRI and snore acoustic recordings. The synchronized image and acoustic information successfully characterize the sites of temporal obstruction during sleep-disordered breathing events.
