Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 4 .3 cm from the carina . An enteric tube courses through the stomach with side port in the stomach , and tip off the inferior borders of the film . Right sided central venous catheter tip terminates in the proximal right atrium . Heart size is normal . The aorta is diffusely calcified . Mediastinal and hilar contours are otherwise within normal limits . Lungs are hyperinflated with severe upper lobe predominant emphysematous changes , more pronounced in the right lung than on the left . 12 mm nodular opacity projecting over the right mid lung field is present . Patchy opacities in the lung bases may reflect atelectasis . No focal consolidation , pleural effusion or pneumothorax is detected . No acute osseous abnormality is seen .
    OUTPUT:
    
1 . Standard positioning of the endotracheal and enteric tubes . 2 . Severe upper lobe predominant emphysema . 3 . 12 mm nodular opacity projecting over the right mid lung field . Further assessment with chest CT on a nonemergent basis is recommended , if no prior exams are available for comparison . 4 . Bibasilar patchy opacities , likely atelectasis .
