Comparison of the static RBC and barrier chemical shifts, linewidths, and phases derived using the barrier Voigt model in healthy volunteers and subjects with IPF during the first second of breath-hold. The RBC phase has been set to 0° as a reference. Two derived metrics, RBC:barrier ratio and the difference in chemical shift between the RBC and barrier peak, are also compared. The black bar with the asterisk indicates statistical difference between groups (P < 0.05)
