Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac silhouette is unremarkable . Emphysematous changes are seen throughout the lungs . Reticular opacities are seen in the bilateral lower lung fields . Somewhat increased opacity is noted in the right mid lung in comparison to the recent CT chest including a peripheral nodular opacity , not definitively seen on prior examination . No large pleural effusion or pneumothorax is present .
    OUTPUT:
    
1 . New subtle right mid lung opacity , which in the appropriate clinical context , may be related to aspiration or pneumonia . 2 . A more discrete nodular opacity in the right midlung , which may be due to the same process . Follow - up chest radiograph is recommended to document resolution and to exclude the less less likely possibility of a lung cancer as a cause of this finding .
