Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is moderately enlarged , but stable from the prior examination . The aorta is tortuous and calcified . Chronic scarring involving the left upper lobe is not changed in appearance and is better characterized on recent CT from ___ . A left lower lobe opacity is improved from the prior radiographs on ___ and likely represents a combination of scarring and possible resolving infection in that area . Right upper lobe opacities , presumably due to fibrosis , are also not significantly changed . No pleural effusion or pneumothorax . No new focal consolidation is identified .
    OUTPUT:
    
Bilateral upper lobe opacities are stable are most consistent with scarring , better characterized on prior CT examinations on ___ and ___ . Left lower lobe opacity is minimally improved from the prior radiographs on ___ and likely represents a combination of scarring and improving infection in that area . Given the patient 's multifocal areas of scarring and opacity , acute infection is difficult to exclude on radiography . Given that , no definite new focal consolidation is identified .
