Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , but the heart size , mediastinal , and hilar contours are normal . The tip of the endotracheal tube is difficult to identify , as it is superimposed on the enteric tube . However , correlation with the CTA head and neck suggests that the tip is approximately 3 .0 cm above the carina . Bibasilar subtle opacities may reflect changes from aspiration . No pleural effusions or pneumothorax . Enteric tube courses below the left hemidiaphragm , curls in the stomach , and courses out of view .
    OUTPUT:
    
1 . Endotracheal tube tip approximately 3 .0 cm above the carina . 2 . Subtle bibasilar opacities may reflect changes from aspiration . Imaging followup to rule out worsening consolidation / aspiration is recommended .
