Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are slightly low . No focal consolidation , pleural effusion , or pneumothorax is seen . Mild pulmonary vascular prominence may be exaggerated by low lung volumes . Heart and mediastinal contours are also exaggerated by low lung volumes . An enteric catheter terminates in the epigastric region likely within the distal stomach . An endotracheal tube tip terminates approximately 3 .5 cm above the carina . There is right acromioclavicular separation , incompletely imaged . A small ossified fragment superior to the left distal clavicle is likely chronic .
    OUTPUT:
    
1 . Appropriate endotracheal tube positioning . 2 . Right acromioclavicular separation , incompletely imaged . Shoulder radiographs are recommended . 3 . Small bony fragment adjacent to the left distal clavicle , which may be chronic in nature . But given history of recent trauma , correlation for pain at this site is recommended . Findings discussed with ___ by ___ by telephone at 9 :35 a .m . on ___ at the time of discovery of these findings .
