An enteric tube courses below the diaphragm with the tip out of field of view . It is likely a post-pyloric position . There is improved aeration at the right base , though there are persistent bibasilar opacities , likely representing residual pneumonia . The apices of the lungs are clear . There is no pulmonary edema . There is no pleural effusion or pneumothorax . Again , subcutaneous air is noted overlying the neck . The cardiomediastinal silhouette is normal .
    OUTPUT:
    
Persistent bibasilar opacities , though there is interval improvement in the aeration at the right base .
