Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . The aorta is tortuous . Allowing for differences in technique , mediastinal and hilar contours are unremarkable . There is volume loss in the right hemithorax with scarring at the right apex that is presumably post-surgical . Mild chronic - appearing compression deformities are poorly visualized along the upper thoracic spine ; although unlikely to represent acute fractures , there may be some increase in the degree of attenuated body heights at one or more levels since the prior CT from several years ago .
    OUTPUT:
    
Mild mid thoracic vertebral compression fractures , similar to slightly increased since the prior CT from ___ ; although not fully characterized , probably chronic . If symptoms refer to the thoracic spine , further imaging assessment could be given consideration .
