Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is mildly enlarged . The mediastinal and hilar contours are unremarkable . There is mild upper zone vascular redistribution suggestive of mild pulmonary vascular congestion . Small bilateral pleural effusions are present . More focal opacities in the lung bases may reflect areas of atelectasis but infection is not excluded . There appears to be background hyperinflation suggestive of underlying COPD . 11 mm nodular opacity projects over the right upper lung field . There is no pneumothorax . No acute osseous abnormality is visualized .
    OUTPUT:
    
1 . Mild cardiomegaly with mild pulmonary vascular congestion . 2 . Small bilateral pleural effusions with bibasilar patchy opacities , likely compressive atelectasis , though infection is not excluded in the correct clinical setting . 3 . 11 mm right upper lobe nodular opacity . Correlation with nonemergent CT is recommended for further assessment .
