    INPUT: In comparison to the chest radiograph obtained 1 .5 hours prior , no significant changes are appreciated . An NG tube passes into the stomach and outside the field of view . Previously identified mid left lung opacity is better appreciated . Retrocardiac and right lower lung opacities are essentially unchanged .
