    INPUT: The lateral radiograph is suboptimal , severely limited by motion artifact and obscured by the arms . The patient is slightly rotated to the right , somewhat limiting the evaluation . The lung volumes are slightly low , similar to the prior study . There is new atelectasis at the right base . The heart is top normal . Allowing for rotation , the mediastinal and hilar contours are likely normal . There is no large pleural effusion or pneumothorax . The aorta and main thoracic vessels are heavily calcified .
    OUTPUT:
    
Low lung volumes and new atelectasis at the right base . No evidence of pneumonia .
