Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . There is mild unfolding of the thoracic aorta . The mediastinal and hilar contours are otherwise unremarkable . There is coarse hazy and streaky opacification involving the right mid to lower lung . Opacities the left lower lobe and lingula are not specific and could be seen with atelectasis or bronchopneumonia . Lungs are hyperinflated , and noting irregular pulmonary architecture , emphysema is suspected . There is no pleural effusion or pneumothorax . Small osteophytes are noted along the thoracic spine .
    OUTPUT:
    
Low lung opacities , without prior studie for comparison , which may be due to acute infection but more chronic scarring could yield a similar appearance . Irregular pulmonary architecture and scarring are concerning for emphysema .
