Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is top normal in size . Mediastinal contours are unchanged . Prominence of the hila bilaterally is unchanged . Low lung volumes are present which result in crowding of the bronchovascular vascular structures . Mild pulmonary vascular congestion may be present . Streaky bibasilar opacities are nonspecific and could reflect atelectasis though infection is not excluded . No pleural effusion or pneumothorax is identified . Ossific density within the right acromiohumeral interval may reflect a loose body .
    OUTPUT:
    
Low lung volumes with streaky bibasilar opacities possibly reflective of atelectasis . Clinical correlation is recommended to exclude infection .
