Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Kyphotic positioning slightly limits assessment . Lung volumes are low . Cardiac , mediastinal and hilar contours are unchanged with the heart size top - normal . No pulmonary vascular engorgement is present . Patchy opacities in the lung bases likely reflect areas of atelectasis in the setting of low lung volumes , and appear relatively unchanged . No pleural effusion or pneumothorax is present . Clips are noted projecting over the left neck . The osseous structures are diffusely demineralized with loss of height of several mid and lower thoracic vertebral bodies , findings which appear relatively unchanged .
    OUTPUT:
    
Limited study due to kyphotic positioning . Low lung volumes with probable bibasilar atelectasis .
