Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal radiograph of the chest demonstrates interval placement of endotracheal tube which terminates 5 .5 cm above the level of the carina . There is also a new feeding tube which projects over the expected course of the esophagus and enters the stomach with side port below the gastroesophageal junction . The lung volumes are low , and could account for the relative increase in opacification of the right lower lung due to vascular crowding . The heart size is difficult to assess due to low lung volumes but is not significantly changed since the prior study . There is no pneumothorax or large pleural effusion .
    OUTPUT:
    
Opacification of the right lower lung could be completely explained by low lung volumes causing vascular crowding . Endotracheal tube and feeding tube in standard position .
