We present a method for simultaneous multi-slice airway collapsibility measurement based on sparse golden-angle radial CAIPIRINHA, with acceleration factor up to 33.3. We present data from patients with obstructive sleep apnea and normal controls. One interesting finding is that a narrower airway site does not always correspond to higher collapsibility. This finding may be of interest to sleep surgeons. Our results also suggest that both compliance and P_close were significantly different between healthy controls and OSA patients (P<0.001), and both measures can potentially serve as biomarkers.
