Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . The heart size is top normal . Mediastinal and hilar contours are unremarkable , and no pulmonary vascular congestion is present . Low lung volumes limits the assessment of the lung bases , with streaky bibasilar airspace opacities potentially reflecting atelectasis , but infection can not be excluded , particularly in the right lung base . No pleural effusion or pneumothorax is seen . No acute osseous abnormalities identified .
    OUTPUT:
    
Low lung volumes limit assessment of the lung bases . Streaky opacities in the lung bases could reflect atelectasis but infection , particularly of the right lung base , can not be excluded . Consider repeat radiographs with improved inspiratory effort for better assessment of the lung bases .
