Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Interval placement of an endotracheal tube is seen , terminating approximately 4 cm above level of the carina . Enteric tube is seen coursing below the level of the diaphragm , terminating in the proximal stomach , and could be advanced that it is well within the stomach . There are low lung volumes . The mediastinum appears widened , also noted on the prior study although more conspicuous on the current study . Unclear whether this relates to differences in inspiration and technique , correlate with concern for mediastinal process . Clinical concern for acute mediastinal process , chest CTA should be considered . Opacity at the left costophrenic angle may relate to overlying soft tissue although an underlying atelectasis or effusion not excluded . No pneumothorax is seen .
    OUTPUT:
    
Endotracheal tube in appropriate position . Enteric tube terminating in the proximal stomach , could be advanced a that it is well the neck . There appears to be gaseous distention of the stomach at time of the image acquisition . Persistently widened mediastinum , more conspicuous on this study than on the prior study . If clinical concern for acute mediastinal process , consider chest CTA . Opacity at the left costophrenic angle may relate to overlying soft tissue although underlying atelectasis or pleural effusion not excluded
