    INPUT: ET tube ends 2 .3 cm above the carina . Right jugular line has been pulled back and is at the junction of jugular vein and superior vena cava . NG tube is in distal stomach . Right lung opacities with elevation of hemidiaphragm are unchanged , please refer to yesterday 's CT . Left lower lung opacities are also stable . There is no pneumothorax . Small bilateral pleural effusions are unchanged .
    OUTPUT:
    
1 . Tubes and lines are in adequate position . 2 . Bilateral opacities mostly in the right lung are compatible with pneumonia as shown on previous CT . Right upper lobe increased density and elevation of the right hemidiaphragm could be due to sequela from prior radiation therapy .
