    INPUT: Heart size is mild to moderately enlarged . The aorta is tortuous . Atherosclerotic calcifications are present within the aortic arch . The pulmonary vasculature is normal . Lungs are clear without focal consolidation . Minimal blunting of the costophrenic angles posteriorly on the lateral view may suggest the presence of tiny effusions or pleural thickening . Lungs are hyperinflated with flattening of the diaphragms suggestive of COPD . No pneumothorax is identified . Multilevel degenerative changes are present within the thoracic spine with anterior bridging osteophytes .
    OUTPUT:
    
No evidence of pulmonary edema or pneumonia . Probable COPD . Possible trace bilateral pleural effusions versus pleural thickening .
