Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the prior outside facility chest radiograph performed 2 hr earlier , there has been interval repositioning of the endotracheal tube , which now terminates 4 .0 cm above the carina . Enteric tube terminates in the distal stomach / proximal duodenum . Minimal left retrocardiac opacity likely represents atelectasis given rapid interval improvement since the recent radiograph . Superimposed infection could be considered in the appropriate clinical setting . There is otherwise no focal consolidation , sizeable pleural effusion or pneumothorax . Mild pulmonary vascular congestion . Heart size appears ___ , ___ be due to portable technique . No acute osseous abnormalities identified . Right lower quadrant 4 x 2 cm opacity might represent liver or adrenal or less likely renal finding . Assessment with US is to be considered .
    OUTPUT:
    
1 . ETT terminates 4 .0 cm above the carina . 2 . NGT in distal stomach / proximal duodenum . 3 . Mild pulmonary vascular congestion . 4 . Left retrocardiac atelectasis versus infection . Right lower quadrant 4 x 2 cm opacity might represent liver or adrenal or less likely renal finding . Assessment with US is to be considered .
