Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size is mildly enlarged . The aorta is diffusely calcified and tortuous . Mediastinal and hilar contours are unremarkable . Lungs are hyperinflated with flattening of the diaphragms , findings suggestive of COPD . No pulmonary edema is present . Scarring is noted within the lung apices , as well as a linear opacity within the left mid lung field which may reflect an additional site of scarring or subsegmental atelectasis . Streaky opacities in the lung bases may reflect atelectasis , but no focal consolidation or pneumothorax is present . Minimal blunting of the costophrenic angles could suggest pleural thickening or trace pleural fluid . No acute osseous abnormality is demonstrated . The distal right clavicle may have been surgically resected with elevation of the right distal clavicle relative to the acromion , findings suggestive of chronic injury .
    OUTPUT:
    
Bibasilar atelectasis and or scarring . Possible trace bilateral pleural effusions versus pleural thickening .
