Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , tip approximately 2 .7 cm above the carina . An NG tube is present , tip extends beneath off film . The does appear to be any side - port in the region of the GE junction , not clearly beyond it . Again seen is a PICC line with the tip near the GE junction , possibly over the upper most right atrium . No pneumothorax detected . There is increased retrocardiac density with air bronchograms , consistent with left lower lobe collapse and / or consolidation and blunting of left costophrenic angle . This is overall similar the prior study , but the hemidiaphragm is less well seen on today 's study , suggesting interval worsening . New slight leftward shift of the cardiac silhouette suggests volume loss at the left lung base . Again seen is hazy somewhat patchy opacity at the right base medially , , consistent with less pronounced atelectasis / infiltrate . . No right effusion . Mild upper zone redistribution could be accentuated by low lung volumes . Doubt overt CHF .
    OUTPUT:
    
Left lower lobe collapse and / or consolidation again seen , probably slightly worse . There is also evidence for new volume loss at the left lung base , reflected by slight leftward shift of the mediastinum . Patchy opacity right base is unchanged compared with 1 day earlier , but does appear more extensive compared with ___ .
