What should be done to correct a lateral projection of the sternum showing superimposed ribs?

• A. Adjust the mA settings
• B. Ensure that the patient is not rotated
• C. Change the imaging technique
• D. Increase exposure time

Answer: (B)

To achieve a clear lateral projection of the sternum without superimposed ribs, ensuring that the patient is not rotated is essential. In a lateral view, proper positioning is critical; even slight rotation can cause overlapping of the ribs, obscuring the visibility of the sternum. Maintaining an accurate lateral position allows for a true profile of the sternum to be captured, enabling better interpretation and diagnosis.

Adjusting the mA settings or changing the imaging technique may not directly address the positioning issue that causes the superimposition of ribs. While exposure time may influence image quality, without correcting the patient's positioning, those adjustments would not resolve the core problem of superimposed anatomical structures. Proper patient alignment is fundamental in obtaining quality radiographic images, particularly in lateral projections.
