An excessive lordotic appearance on an AP neonatal or infant chest projection is often due to the central ray being centered too superiorly, causing the ribs to slope sharply downward at the anterior aspect of the lungs. This will give the anterior ribs a downward projection while the posterior ribs will appear horizontally. Therefore, option 1 and 3 are correct, but option 2 is incorrect as there will be no upward projecting ribs. Option 4 is also incorrect as a perpendicular central ray would not cause excessive lordotic appearance.
