    INPUT: There are low lung volumes . The cardiomediastinal silhouettes are stable and within normal limits . The bilateral hila are unremarkable .

There is no pneumothorax or pleural effusion . An exaggerated thoracic kyphosis with several mid thoracic vertebral body compression deformities is unchanged in appearance in comparison to prior exams .
    OUTPUT:
