Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is limited due to low lung volumes and significant artifact from trauma board . Allowing for this limitation , the endotracheal tube is seen ending approximately 4 cm above the carina and the esophageal tube ends below the gastroesophageal junction , with the tip out of view . Low lung volumes accounting for bronchovascular crowding . No cardiomegaly is identified . Apparent widening of the vascular pedicle is likely due to position and low lung volumes .
    OUTPUT:
    
Appropriate position of the endotracheal and esophageal tubes . Low lung volumes .
