Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is in place , tip above the level of the clavicular heads , approximately 5 .8 cm above the carina . An NG tube is present , tip extending beneath diaphragm , off film . A right IJ PICC line is present , tip at the confluence of subclavian and brachiocephalic veins , in the region of the proximal - most SVC . No pneumothorax is detected . Compared with earlier the same day , much of the left mid and lower zones of the left lung remain dense opacified . However , there has been some degree of interval aeration in the mid zone laterally , extending into the left lung apex . Mild residual hazy opacity is seen in the left upper and lateral left mid zones . Allowing for rotated positioning , no definite leftward shift of the mediastinum is identified , though subtle displacement would be difficult to completely exclude . In the right lung , there is vascular plethora and atelectasis , slightly increased , without frank consolidation or gross effusion .
    OUTPUT:
    
Interval improvement in the aeration , predominantly involving the lateral mid zone . Mild residual hazy opacity is seen in the left upper and lateral left mid zones . The left base remains densely opacified , with obscuration of left hemidiaphragm . If clinically indicated , CT could help to better define the etiology of the left lung opacification ( pleural fluid versus atelectasis , versus consolidation . ) Atelectasis and mild vascular plethora in the right lung , slightly more pronounced than on the film from earlier the same day . No frank consolidation or gross effusion on the right . ET tube tip lies above the level of the clavicular heads . Clinical correlation regarding possible advancement is requested .
