Which view is best for evaluating the C7–T1 region when the lateral view is inadequate?

• A. Cervicothoracic (swimmer’s) view or other specialized projections.
• B. AP projection.
• C. Lateral thoracic view.
• D. Odontoid view.

Answer: (A)

Visualizing the cervicothoracic junction requires reducing shoulder overlap. The lateral view often cannot separate C7–T1 because the shoulders lie over the lower neck and upper thoracic area. The cervicothoracic (swimmer’s) view moves the shoulders away from the spine with the arm placement and body rotation, which clears the C7–T1 region and provides a clearer image of alignment, fractures, or other pathology at that junction. If this view isn’t possible or if a different angle is needed, other specialized projections that similarly move or angle the shoulders can be used to visualize that area. In contrast, an AP projection, a lateral thoracic view, or an odontoid view do not effectively address the shoulder overlap at C7–T1.
