    INPUT: Low lung volumes limits assessment as does multiple overlying wires . Patient is status post endotracheal tube placement which appears 5 cm above the level of the carina . An enteric tube traverses the thorax in an uncomplicated course . The heart appears top - normal in size . Mediastinal contour appears normal . Mild hilar prominence with perihilar opacity could reflect bronchovascular crowding , possibly aspiration or atelectasis . There is no large pleural effusion . No pneumothorax . Bony structures are grossly intact .
    OUTPUT:
    
ET and enteric tube positioned appropriately . Perihilar opacities may reflect bronchovascular crowding versus aspiration versus atelectasis .
