Fig. 2.
Radiological injury propagation in two representative rats. Images were obtained after acid aspiration (after a period of stabilization of 1 h) and were repeated hourly. Coronal (A) and axial (B) images are shown. One animal (top panel) showed rapidly spreading radiological infiltrates and died after 2 h of ventilation. The second animal (bottom panel) had limited injury propagation and survived until the end of the experiment.
