Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is slightly limited by patient rotation . Cardiac silhouette size appears within normal limits . Mediastinal and hilar contours are grossly unremarkable . Lungs are hyperinflated with attenuation of pulmonary vascular markings towards the apices likely reflective of underlying emphysema . Streaky opacities in the lung bases may reflect areas of atelectasis . No focal consolidation , large pleural effusion , or pneumothorax is identified . No acute osseous abnormality is demonstrated .
    OUTPUT:
    
Limited study . Streaky atelectasis within the lung bases . Emphysema .
