Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The lung volumes are relatively low . Calcifications projecting over both lung fields are consistent with pleural plaques which appears progressed as compared to the prior study . Lateral left mid to lower hemithorax opacity most likely may relate to calcified pleural plaques on the frontal view . However , on the lateral view , the costophrenic angles are sharp and no definite focal consolidation is seen . There is severe compression of a lower thoracic vertebral body also seen increased since ___ , ___ as well as slightly increased from CT from ___ . The cardiac silhouette is moderately enlarged . The aortic knob is calcified . Additional compression deformities in the upper lumbar spine are not well evaluated on this study . There is apparent prominence of the interstitial markings . This may in part relate to the overlying calcified pleural plaques , however , may be chronic as noted on prior studies .
    OUTPUT:
    
1 . Extensive bilateral calcified pleural plaques suggest prior asbestos exposure . 2 . Enlarged cardiac silhouette . 3 . Marked compression of a lower thoracic vertebral body appears increased since ___ .
