Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette is mildly enlarged but stable in size . Mediastinal and hilar contours are normal . There remains mild volume loss in the right hemithorax with areas of pleural and parenchymal scarring . Left lung is grossly clear , and there is no evidence of a left pleural effusion . Known left apical nodular opacity on recent CT of the chest is not clearly visualized . Multiple calcified pleural plaques are present bilaterally , right greater than left , suggesting prior asbestos exposure .
    OUTPUT:
    
Previously reported left apical nodular opacity on CT is not clearly visualized radiographically , but CT would be more sensitive than radiographs for evaluating this finding .
