    INPUT: A nasogastric tube enters the stomach , its distal course not imaged beyond the gastric cardia . A left - sided PICC line terminates at the cavoatrial junction . The cardiac , mediastinal and hilar contours are stable . Small - to - moderate layering pleural effusions are suspected . A mild interstitial abnormality suggests pulmonary congestion , but similar to perhaps somewhat improved . Right apical pleural thickening is stable and persistent relative elevation of the right hemidiaphragm reflects postsurgical volume loss .
    OUTPUT:
    
Suspected pleural effusions and findings suggesting pulmonary congestion .
