Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral chest radiographs were provided . There is no focal consolidation . There is stable elevation of the right hemidiaphragm . It is difficult to ascertain on this study whether obscuration of the posterior portion of the right hemidiaphragm is due to a pleural effusion or atelectasis . Increased prominence of interstitial markings , on a background of chronic lung disease consistent with mild pulmonary edema . Linear opacity in the right lung likely represents fluid in the fissure . There is no pneumothorax . The cardiomediastinal silhouette is enlarged and stable . The imaged upper abdomen is unremarkable . The bones are intact .
    OUTPUT:
    
1 . Stable elevation of the right hemidiaphragm . It is difficult to differentiate whether obscuration of the posterior margin of the right hemidiaphragm is due to atelectasis or pleural effusion . Recommend a decubitus film for further evaluation . 2 . Mild pulmonary edema . 3 . Chronic interstitial lung disease .
