    INPUT: The extreme upper edge of the right and left chest is excluded from the film . An ET tube is present , tip approximately 4 .1 cm above the carina , at the level of the mid clavicular heads . A right IJ central line is present , tip overlying cavoatrial junction . No pneumothorax detected . Heart size is at the upper limits of normal , not significantly changed . Innumerable small , irregular opacities are seen throughout both lungs , with a somewhat peripheral distribution . In addition , there appear to be slightly coarsened interstitial markings diffusely in both lungs . These are similar , but , on the left , slightly more pronounced . No obvious cavitation is appreciated . No left pleural effusion . The right lower chest is excluded from the film , but no gross right effusion is seen .
    OUTPUT:
    
1 . ET tube tip at level of the clavicular heads approximately 4 .1 cm above the carina . 2 . Innumerable small patchy opacities seen throughout both lungs , similar to yesterday 's radiograph , but probably increased on the left . Given the clinical setting , these are concerning for multifocal airspace disease , possibly septic emboli .
