Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . The patient is status post sternotomy . A dual - lead pacemaker / ICD device with leads terminating in the right atrium and ventricle appears unchanged . The heart is again mildly enlarged . The mediastinal and hilar contours appear unchanged . There are no pleural effusions or pneumothorax . Pleural plaques are widespread . On this examination , compared to the prior radiograph , there is vague hazy opacity projecting over the right upper lung . It appears similar , however , to more recent chest CT imaging , however , and probably less severe . Mild superior endplate compression deformity of vertebral body situated at the thoracolumbar junction appears unchanged .
    OUTPUT:
    
Persistent asymmetric hazy opacity projecting over the right upper lung compared to the left , but similar to a decrease since the prior chest CT . Although difficult to exclude a subtle acute process , the appearance is likely chronic . If symptoms were to persist , however , then short - term repeat radiographs could be given consideration to exclude pneumonia .
