Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . This limits assessment of the lung bases where there are patchy ill - defined opacities noted , possibly reflecting atelectasis but infection or aspiration can not be excluded . Crowding of the bronchovascular structures is present , but no overt pulmonary edema is identified . Mild enlargement of the cardiac silhouette is accentuated by the low lung volumes . Mediastinal and hilar contours are unremarkable . No pneumothorax or pleural effusion is present . There are no acute osseous abnormalities .
    OUTPUT:
    
Low lung volumes limit assessment of the lung bases . Bibasilar airspace opacities could reflect atelectasis but infection or aspiration is not excluded . Consider repeat views when the patient is able to take an improved inspiratory effort for further assessment .
