    INPUT: The lungs are hyperexpanded . There is a background of emphysema . There is a questionable opacity in the right lower lung , which would be better evaluated with chest CT . Calcifications along the left chest laterally suggest calcified pleural plaques . Scarring may account for obscuration of the left costophrenic angle . There may also be calcified pleural plaques projecting over the right lung laterally as well . No pneumothorax is seen . Heart size is normal . The aorta is calcified , indicating atherosclerosis . The mediastinal and hilar contours are normal . The pulmonary vasculature is normal . There are no acute osseous abnormalities .
    OUTPUT:
    
Questionable opacity in the right lower lung , which would be better evaluated with chest CT . Calcifications along the left chest suggesting calcified pleural plaques . Left basilar opacity may be due to scarring .
