Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Slightly rotated positioning . An ET tube is present , tip approximately 4 .2 cm above the carina . An NG tube is present , tip extends beneath diaphragm . The sideport if present with lie above the GE junction . Cardiomegaly is unchanged . There is evidence of CHF , with upper zone redistribution , vascular plethora , interstitial edema and diffuse vascular blurring , unchanged . There is prominent opacity in the right lower zone , unchanged . This likely represents a combination of a pleural effusion with underlying collapse and / or consolidation . Increased retrocardiac density is unchanged . However , the left pleural sulcus is better seen , suggesting decrease in size of left pleural effusion .
    OUTPUT:
    
NG tube tip lies beneath the diaphragm . However , if there is a side - port , it may lie above the GE junction . Otherwise , essentially unchanged compared with ___ at 02 :37 . The left costophrenic sulcus is now better seen . Cardiomegaly , CHF and bibasilar opacities , are similar to the prior study .
