Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: No pneumothorax or pleural effusion is detected . Compared to the prior film , the right paratracheal opacity is more readily visible . I suspect this is due to differences in technique , but slight interval enlargement can not be entirely excluded . The trachea in this area does not appear narrowed . Otherwise , the cardiomediastinal silhouette , including the hilar adenopathy , is unchanged . No CHF or focal consolidation . Mild patchy opacity in the right cardiophrenic region is slightly improved . Platelike atelectasis in the right mid zone is new .
    OUTPUT:
    
1 . No pneumothorax detected . 2 . Right paratracheal opacity is more prominent --___ due to technique or interval slight enlargement . 3 . New right midzone platelike atelectasis . Slight interval improvement in right cardiophrenic opacity , likely also atelectasis .
