Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable . There is persistent mild relative elevation of the right hemidiaphragm . There are probably small bilateral pleural effusions . Minimal vague opacity projects over the right upper lung , similar to the prior appearance , although more generalized opacification was present on the prior examination . Compared to earlier radiographs , this area of opacity is similar and so may be a more chronic process . Lines , tubes and drains have been removed .
    OUTPUT:
    
Patchy opacity in the right upper lobe , although potentially chronic . If there is clinical concern for pneumonia , short - term followup radiographs may be helpful . Very small suspected pleural effusions .
