Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube is low lying terminating approximately 1 .8 cm from the carina . An enteric tube tip is within the stomach however the side port appears to be at the level of the gastroesophageal junction and should be advanced slightly for optimal positioning . Low lung volumes are present . Heart size appears mildly enlarged , but exaggerated by the presence of low lung volumes . Mediastinal and hilar contours are unremarkable with the widening of the superior mediastinum accounted for by the low lung volumes and supine positioning . Crowding of bronchovascular structures is present without overt pulmonary edema . There is minimal atelectasis in the lung bases , but no focal consolidation . No pleural effusion or pneumothorax is detected on this supine exam . Irregularity of the left seventh lateral rib cortex suggests a nondisplaced fracture .
    OUTPUT:
    
1 . Low lying endotracheal tube . Recommend retraction by approximately 2 cm . 2 . Enteric tube tip within the stomach , but side port at the level of the gastroesophageal junction . Recommend slight interval advancement for optimal positioning . 3 . Nondisplaced left seventh lateral rib fracture .
