    INPUT: There has been interval removal of an enteric tube . Low lung volumes and bibasilar airspace opacities are unchanged , likely representing a combination of pleural effusions and atelectasis . A superimposed infectious process is difficult to exclude . Pulmonary vascular congestion and mild pulmonary edema having improved . There is persistent moderate dextroscoliosis of the upper thoracic spine . The cardiomediastinal silhouette is largely obscured by the bibasilar airspace opacities .
    OUTPUT:
    
1 . Slight interval improvement in pulmonary vascular congestion and mild pulmonary edema . 2 . Persistent low lung volumes and bibasilar opacification likely representing a combination of pleural effusion and atelectasis . Superimposed pneumonia or aspiration is difficult to exclude .
