MRc spirometry during GI
  • Data are presented as absolute values (% of predicted). MRI: magnetic resonance imaging; VCI: inspiratory vital capacity; FEV1: forced expiratory volume in one second; PEF: peak expiratory flow; Raw,tot: total airway resistance; ITGV: intrathoracic gas volume; RV: residual volume; TLC: total lung capacity; DL,CO: diffusing capacity of the lung for carbon monoxide; DL,CO,SB: single-breath DL,CO; VA: alveolar volume; MRc: magnetic resonance-compatible; GI: glossopharyngeal insufflation; VCI,MRI: VCI measured during MRI acquisition; SVCE,MRI: expiratory slow vital capacity after GI during MRI acquisition.
