Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Suspect background hyperinflation , consistent with COPD . There is moderate cardiomegaly , with splaying of the carina . There is upper zone redistribution and diffuse vascular blurring , consistent with CHF . Some Kerley B lines are noted . There is hilar prominence , right > left . There are small bilateral effusions . The possibility of an underlying infectious infiltrate would be difficult to exclude at the bases . Prominence of the interstitial markings and presence of effusions are new compared with the ___ radiograph and the cardiac silhouette is also more pronounced . Right hilum is more prominent cmpared with ___ . Advanced degenerative changes of the spine , with mild wedging of the presumptive T12 vertebral body , is unchanged .
    OUTPUT:
    
1 . Cardiomegaly , slightly worse compared with ___ . 2 . Interstitial edema , Kerley B lines and small effusions , consistent with CHF , which appears new compared with a ___ CTA . Given the limited degree of upper zone redistribution , the differential includes other causes of increased institial markings , but given the relatively rapid onset and presence of small effusions , CHF is most likely . 3 . Interval increase in right hilar prominence . This may be related to the CHF findings . However , follow - up radiographs to confirm return to ___ baseline is recommended . 4 . In the appropriate clinical setting , underlying infectious infiltrate would be difficult to exclude .
