Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post median sternotomy and CABG . The lungs are hyperinflated with flattening of the diaphragms compatible with emphysema . The heart size is normal . Mediastinal and hilar contours are unchanged . Increased interstitial opacities are seen diffusely , with more focal confluent opacity seen within the right peripheral mid lung field . Coarsened interstitial markings are also seen predominantly at the lung bases and along the periphery compatible with known pulmonary fibrosis . No large pleural effusion or pneumothorax is demonstrated . No new areas of focal consolidation clearly noted . There are no acute osseous abnormalities .
    OUTPUT:
    
Little interval change compared to the previous radiograph with no new areas of focal consolidation seen . Mild interstitial pulmonary edema superimposed on a background of chronic interstitial lung disease with evidence of severe emphysema and fibrosis . Previously described regions of either multifocal pneumonia or cryptogenic organizing pneumonia seen on prior CT are not as well assessed on this radiograph .
