Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral chest radiographs demonstrate no significant change in right upper lobe post-radiation treatment fibrosis and traction bronchiectasis with mild elevation of the right hilum . The lungs are hyperinflated with bilateral upper lobe emphysema . Ovoid opacity in the right upper lobe likely represents an area of fibrosis as seen on prior CT from ___ . The lungs are otherwise well expanded and clear and the pleural surfaces are normal without pleural effusion or pneumothorax . Mild mediastinal shift is unchanged from ___ and is likely related to post-radiation scarring and fibrosis . Heart size , mediastinal contour and hila are unchanged in configuration from ___ . The visualized osseous structures are unremarkable .
    OUTPUT:
    
1 . No evidence of acute cardiopulmonary process . 2 . Chronic right suprahilar scarring , fibrosis and traction bronchiectasis is unchanged however can not exclude underlying subtle lesion which would be better assessed with CT . 3 . Right upper lobe ovoid opacity likely represents an area of scarring and is best assessed on ___ CT .
