    INPUT: Lung volumes are low . Heart size is accentuated as a result and appears mildly enlarged . Mediastinal and hilar contours are unremarkable . Crowding of the bronchovascular structures is present without overt pulmonary edema . Patchy and streaky opacities in the lung bases likely reflect areas of atelectasis . No focal consolidation , pleural effusion or pneumothorax is present . Fusion hardware within the lower lumbar spine is partially imaged . Compression deformity of a mid lumbar vertebral body as well as mild loss of height anteriorly of a vertebral body at the thoracolumbar junction are of indeterminate age .
    OUTPUT:
    
Low lung volumes with bibasilar atelectasis . Compression deformities within the imaged thoracolumbar spine , age indeterminate .
