Which of the following projections is best for demonstrating the apices of the lungs without bony superimposition?

The AP axial lordotic position is optimal for demonstrating the apices of the lungs without bony superimposition because it effectively angles the X-ray beam to project the apices above the clavicles. This positioning minimizes the interference from bony structures, particularly the shoulder girdles, that may obscure the view of the apices. Achieving a proper lordotic position enhances the visibility of the lung apices, which is often necessary when evaluating for conditions such as tumors or other abnormalities located in these areas.

The other projection options either do not sufficiently elevate the apices above the bony structures or may result in overlapping shadows that hinder clarity. The PA projection, while useful for general lung imaging, does not provide the necessary angling to fully visualize the apices distinctly. The AP projection tends to create more superimposition of the clavicles over the apices, making it less effective for this specific anatomical area. Similarly, while the lateral projection emphasizes different aspects of lung anatomy, it does not directly target the apices in the same way as the lordotic position, thereby making it less suitable for showcasing the apices clearly without obstruction.
