Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Rotated positioning , low lung volumes . An ET tube is present , tip approximately 4 .8 cm above the carina . An NG tube is present , tip beneath diaphragm , overlying stomach . Extensive spinal hardware noted . The heart borders are obscured , but the heart is probably not enlarged . There are diffuse opacities throughout both lungs , with denser left retrocardiac opacity and obscuration of left - greater - than - right hemidiaphragms . Possibility of small effusions can not be excluded . Compared with ___ at 20 : 18 p .m . and allowing for technical differences , there has been possible increase in the degree of hazy opacity in the right and left mid zones , reflecting worsening CHF . Otherwise , findings are overall similar .
    OUTPUT:
    
1 . ET tube as described . 2 . Left lower lobe collapse and / or consolidation , unchanged . 3 . Hazy opacity in both lungs , slightly worse in the midzones , most suggestive of worsening CHF . Possibility of underlying infectious infiltrate is difficult to exclude . 4 . Possible small bilateral effusions .
