Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is intubated . The carina is difficult to discern but the endotracheal tube probably terminates about 2 .5 cm above it . An orogastric tube courses into the stomach , terminating in the antrum to the right of midline . Lung volumes are low . Allowing for technique , the cardiac and mediastinal and hilar contours appear unremarkable . There is mild perihilar fullness bilaterally which is suggestive of venous hypertension . Vague density at the left lung base makes it difficult to exclude the possibility of a developing opacity there , which would most commonly be due to atelectasis .
    OUTPUT:
    
Low lung volumes with a mild hilar fullness suggesting pulmonary venous hypertension . Vague left basilar opacity , not specific but most commonly this would be due to developing atelectasis .
