Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , tip approximately 6 .3 cm above the carina , at the level of the upper clavicular heads . Right IJ central line tip lies in the region of the SVC / RA junction . An NG type tube is likely present , not well visualized . It most likely extends beneath the diaphragm to overlie the proximal stomach , but a be more completely and better visualized on films obtained with the increased penetration . There are low inspiratory volumes . There is dense opacification of the mid and lower zones of left lung , with obscuration of the cardiac silhouette and hemidiaphragm . This has clearly increased compared with ___ and ___ . Aside from minimal atelectasis in the right upper zone and possible minimal upper zone redistribution , the right lung is grossly clear , without focal consolidation or effusion . Based on the appearance of the right heart border , the cardiomediastinal silhouette likely remains midline .
    OUTPUT:
    
ET tube 6 .3 cm above the carina , relatively high . Clinical correlation regarding possible advancement is requested . Dense opacification of the left mid and lower lung zones , of uncertain etiology . Differential includes pleural effusion , consolidation , atelectasis or a combination thereof . Cardiomediastinal silhouette remains grossly midline . Aside from possible minimal upper zone redistribution and minimal atelectasis at the right lung apex , the right lung is grossly clear , without effusion .
