Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size is normal . The aortic knob is calcified . Mediastinal and hilar contours are unchanged , and known bilateral hilar and mediastinal lymphadenopathy is better appreciated on the recent CT of the chest . Bilateral calcified pleural plaques are noted with mild superimposed opacities in the lung bases possibly reflective of atelectasis . Small bilateral pleural effusions are not substantially changed from the recent chest CT . Approximately 1 cm right apical nodule is re - demonstrated , better assessed on the recent CT . No pneumothorax or pulmonary vascular congestion is demonstrated . No acute osseous abnormality is present .
    OUTPUT:
    
1 . Patchy opacities in the lung bases superimposed on a background of calcified pleural plaques may reflect atelectasis . 2 . Small bilateral pleural effusions , unchanged . 3 . Right apical nodule and bilateral hilar and mediastinal lymphadenopathy are better assessed on recent chest CT .
