    INPUT: Assessment of the chest is somewhat limited by patient rotation . Lung volumes are low . Heart size is mildly enlarged but not substantially changed in the interval . Mediastinal and hilar contours are grossly unchanged . Pulmonary vasculature is not engorged . Minimal streaky right opacity in the right lung base likely reflects an area of atelectasis . No focal consolidation , pleural effusion or pneumothorax is present . There are no acute osseous abnormalities identified .
    OUTPUT:
    
Limited study due to patient rotation . Minimal atelectasis in the right lung base .
