    INPUT: As compared to the prior study , lung volumes have decreased and there are persistent bilateral reticular airspace opacities as well as small to moderate bilateral pleural effusions . Retrocardiac opacification likely represents atelectasis . However , dense consolidation can also exist at this location . The cardiac and mediastinal contours are stable .
    OUTPUT:
    
Interval decrease in lung volumes with continued interstitial opacities consistent with pulmonary edema and likely superimposed infection . Small to moderate bilateral pleural effusions are again seen .
