Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . This accentuates the size of the cardiac silhouette which is likely top normal . Mediastinal and hilar contours are likely within normal limits . There is crowding of the bronchovascular structures , but no pulmonary edema is present . Streaky bibasilar airspace opacities may reflect atelectasis . No pleural effusion or pneumothorax is seen . There are no acute osseous abnormalities .
    OUTPUT:
    
Streaky bibasilar airspace opacities could reflect atelectasis , but infection can not be completely excluded . Repeat radiographs with improved inspiratory effort may be helpful to better assess the lung bases .
