Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is limited by patient rotation . Left - sided pacemaker device with leads terminating in the regions of the right atrium right ventricle appear grossly unchanged . There is moderate cardiomegaly . Low lung volumes persist with crowding of bronchovascular structures and probable mild pulmonary vascular congestion . Linear and patchy bibasilar airspace opacities may reflect atelectasis . No pleural effusion or pneumothorax is seen . Mediastinal and hilar contours are grossly unchanged . S - shaped scoliosis of the thoracolumbar spine with multilevel degenerative changes are again noted . Compression deformity of the T7 vertebral body appears grossly unchanged . Partially imaged is cervical spinal fusion hardware . Remote right - sided rib fractures are again noted .
    OUTPUT:
    
Limited study due to rotation and low lung volumes . Bibasilar atelectasis with probable mild pulmonary vascular congestion .
