Correlations of magnetic resonance imaging-derived parameters [high-density lung volume percentage, tidal volume (TV), and minute ventilation] with biochemical measurements (hydroxyproline content; A, C, E) and histological measurements (pleural thickness; B, D, F), with both doxycycline-fed (Dox) (n = 6) and control (n = 5) cohorts considered. TV demonstrated the strongest correlation with hydroxyproline as seen in C.
