    INPUT: The heart appears mildly enlarged . The mediastinal and hilar contours appear unremarkable aside from mild unfolding along the descending thoracic aorta . There is no pleural effusion or pneumothorax . Streaky medial left basilar atelectasis is most consistent with minor atelectasis . The lungs appear otherwise clear . The bones appear demineralized . Vertebroplasties have been performed along four lower thoracic spinal levels , not completely assessed . Immediately above these , there is a mild loss in height of a vertebral body , but not necessarily acute and difficult to assess . Prior fractures involve the right posterior lateral sixth and seventh ribs , and probably eighth rib , without displacement . On the left , no fracture is identified .
    OUTPUT:
    
No evidence of acute cardiopulmonary disease .
