Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube is noted terminating within the right mainstem bronchus approximately 1 cm beyond the level of the carina . A ___ tube is seen extending into the stomach , and a right subclavian central venous line terminates near the cavoatrial junction . Low lung volumes are noted , resulting in crowding of the bronchovascular structures . The left lung is diffusely opacified relative to the right , likely secondary to the selective right mainstem intubation . Right infrahilar airspace opacities likely reflect atelectasis , although consolidation can not be excluded . There is no pleural effusion or pneumothorax identified . The heart appears mildly enlarged , allowing for portable AP technique . Surgical clips are noted within the right upper quadrant .
    OUTPUT:
    
1 . Selective right mainstem bronchus intubation with resultant increased opacification of the left lung . 2 . Right infrahilar airspace opacities may reflect atelectasis , although underlying pneumonia can not be excluded .
