    INPUT: The heart appears mildly enlarged . The cardiac , mediastinal and hilar contours appear unchanged . There is patchy opacity in the left lower lobe that is probably due to minor atelectasis . Very small bilateral pleural effusions are present . Lungs appear otherwise clear . There is a new moderate anterior wedge compression deformity of a mid to lower thoracic vertebral body since the prior study , although likely chronic . There is a moderate lower thoracic compression deformity and two mild biconcave thoracolumbar compression deformities , which are worse than on the prior study , although again likely chronic .
    OUTPUT:
    
1 . Small pleural effusions and suspected atelectasis at the left lung base . 2 . New , but probably chronic compression deformities .
