    INPUT: Compared to earlier the same day and allowing for differences in technique , the degree of opacification seen in both lungs appears to have progressed slightly , with more opacity now seen in the mid and upper zones on both sides . The possibility of some associated pleural fluid can not be excluded , but much of this is likely accounted for by parenchymal opacification . The cardiac silhouette is now less well seen on both sides due to this opacification . The right paratracheal soft tissues are again noted to be prominent -- ? due to right - sided vascular engorgement . The ET tube lies approximately 5 .3 cm above the carina and the right IJ central line overlies the distal SVC , both similar to the prior film .
    OUTPUT:
    
Worsening opacification of both lungs .
