Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube tip lies 3 .7 cm above the carina . NG tube tip extends beneath diaphragm to overlie the stomach . A right - sided PICC line is again noted . Lead tip is obscured by the EKG marker , but it probably overlies the distal most SVC . No pneumothorax is detected . Cardiomediastinal silhouette is unchanged . Again seen is increased retrocardiac density with probable small left effusion , very slightly improved . Small left effusion would again be difficult to exclude . Hazy opacity in the right cardiophrenic region is also similar to the prior study , but may be slightly more extensive . There is upper zone redistribution and mild vascular blurring , consistent with mild CHF .
    OUTPUT:
    
Increased retrocardiac density consistent with left lower lobe collapse and / or consolidation is very slightly improved . Hazy opacity at the right cardiophrenic region may be very slightly more extensive . Mild CHF .
