Correlations of magnetic resonance imaging (MRI)-derived tidal volume (TV) with pulmonary mechanical measurements: compliance (A), airway resistance (B), and airway elastance (C); correlations of MRI-derived minute ventilation with pulmonary mechanical measurements: compliance (D), airway resistance (E), and airway elastance (F), with both doxycycline-fed (Dox) (n = 6) and control (n = 5) cohorts considered.
