Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a relative lucency of the right upper lung and opacity of the right lower lung , consistent with changes secondary to surgery and radiation . However , the opacity in the right lower lung could also represent acute infectious process . There are diffuse , reticular opacities seen in the left lung . There is obscuration of the aortic knob potentially suggestive of hilar adenopathy and enlargement of the left pulmonary artery consistent with pulmonary hypertension . The pleural surfaces are clear without effusion or pneumothorax .
    OUTPUT:
    
1 . Opacity at the right lung base that may represent postsurgical change or possibly acute infectious process . Further evaluation can be made if prior chest radiographs are submitted for comparison . 2 . Enlargement of the left pulmonary artery consistent with pulmonary hypertension . These findings were entered as a wet read into the ED dashboard .
