Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube tip terminates approximately 5 cm from the carina . An enteric tube is noted looped within the stomach , with the tip coursing off the inferior borders of the film . Low lung volumes are present . The heart size is mildly enlarged . Superior mediastinal contours are widened , and there is crowding of the bronchovascular structures . No overt pulmonary edema is seen . Bibasilar patchy opacities are nonspecific , possibly reflective of atelectasis but infection or aspiration can not be excluded . There is no pleural effusion or pneumothorax . No acute osseous abnormalities are seen .
    OUTPUT:
    
1 . Standard position of the endotracheal and enteric tubes . 2 . Widening of the superior mediastinum . Further assessment with chest CTA is recommended . 3 . Bibasilar patchy opacities may reflect atelectasis in the setting of low lung volumes , but infection or aspiration can not be completely excluded .
