The lungs are hyperexpanded and hyperlucent , consistent with emphysema . No pneumothorax , pleural effusion , or focal consolidation . The heart is mildly enlarged , increased from the prior exam . There is pulmonary vascular congestion but no over pulmonary edema . Prominent reticular scarring at the bilateral apices is probably similar to the prior exam and better characterized on the prior chest CT . No obvious pulmonary mass . No acute osseous abnormality .
    OUTPUT:
