Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is moderately enlarged . There is increasing relative elevation of the right hemidiaphragm which apparently accompanies increasing posterior basilar volume loss and probably a pleural effusion . In addition to perihilar fullness and haziness , there is moderate interstitial abnormality suggesting pulmonary edema . There is no evidence for pleural effusion on the left or pneumothorax .
    OUTPUT:
    
1 . Findings suggesting mild - to - moderate pulmonary edema . 2 . Volume loss and suspected pleural effusion in the right lower lobe with increased relative elevation of the right hemidiaphragm . This appearance may be due to sequelae of cardiac failure with atelectasis , but an infectious etiology is not excluded by this study .
