In the swimmers lateral view of the cervical spine, what caudal angulation is used to better visualize the C7-T1 articulation?

• A. 0 degrees
• B. 2-3 degrees
• C. 3-5 degrees
• D. 6-8 degrees

Answer: (C)

In this view, the goal is to bring the C7-T1 junction into profile by reducing shoulder overlap over the lower cervical spine. A gentle caudal angulation of the x-ray beam accomplishes this by directing the beam slightly toward the feet, which nudges the shoulder girdle downward and away from the cervical region without tilting the spine itself.

The key is using a modest angle: enough to clear the shoulder and reveal C7-T1, but not so large that the lower cervical levels become distorted or foreshortened. If the C7-T1 articulation isn’t yet visible, increase the tilt slightly in small increments until that junction is clearly demonstrated, while keeping the rest of the cervical spine aligned. This approach avoids excessive distortion and provides a better view of the lower cervical spine for accurate assessment.
