Accelerated three-dimensional upper airway MRI using compressed sensing.
In speech-production research, three-dimensional (3D) MRI of the upper airway has provided insights into vocal tract shaping and data for its modeling. Small movements of articulators can lead to large changes in the produced sound, therefore improving the resolution of these data sets, within the constraints of a sustained speech sound (6-12 s), is an important area for investigation. The purp...
متن کاملEvaluation of upper airway collapsibility using real-time MRI.
PURPOSE To develop and demonstrate a real-time MRI method for assessing upper airway collapsibility in sleep apnea. MATERIALS AND METHODS Data were acquired on a clinical 3 Tesla scanner using a radial CAIPIRIHNA sequence with modified golden angle view ordering and reconstructed using parallel imaging and compressed sensing with temporal finite difference sparsity constraint. Segmented airwa...

Study Design. Case series with chart review. Setting. Academic sleep medicine center. Subjects and Methods. The first 20 implanted patients to complete postoperative sleep laboratory testing were assessed. ...
متن کاملUpper airway radiographs in infants with upper airway insufficiency
Upper airway measurements in nine infants considered to be at risk of upper airway insufficiency, six of whom presented after an apnoeic episode, were compared with measurements taken in two age groups of healthy infants. Paired, inspiratory and expiratory, lateral upper airway radiographs were obtained while the infants were awake and breathing quietly. The radiographs of all nine infants demo...
