Dynamic spectroscopy of ¹²⁹Xe replenishment into the barrier and RBC compartments covering the entire lung of both a healthy control (no. 1) and right-lung-injured (no. 9) rat, 5 days postinstillation. (A) Dynamic spectra in control animal. (B) Fit of barrier and RBC signal replenishment in control animal. (C) Dynamic spectra in injured rat. (D) Fit of barrier and RBC signal replenishment in injured rat. Note that the ratio of RBC/barrier signal at saturation is markedly diminished in the injured animal (D) vs. the control animal (B).
