Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low lung volumes , which accentuate the bronchovascular markings . Given this , questionable right perihilar opacity is no longer appreciated and most likely related to vascular structures . Blunting of the costophrenic angles suggest small pleural effusions . There is likely left base atelectasis . Slight prominence of the vasculature may be due to mild pulmonary vascular congestion .
    OUTPUT:
    
Right perihilar opacity is no longer well seen and likely due to vascular structures . Low lung volumes and likely trace bilateral pleural effusions . Left base atelectasis . Possible mild pulmonary vascular congestion .
