What is a recommended strategy to center the patient when ensuring the C7–T1 junction is included in cervical imaging?

• A. Center near T1, elevate shoulders.
• B. Include skull base to T1, depress shoulders, and center near C4.
• C. Center near the pelvis.
• D. Center near C7, rotate head sharply.

Answer: (B)

To clearly visualize the C7–T1 junction, you need to ensure the imaging field includes from the skull base down to T1 and reduce shoulder shadows that often obscure this area. Depressing the shoulders moves them downward and away from the lower cervical region, which helps reveal the cervicothoracic junction rather than having it hidden under the shoulders. Centering the beam near the level of C4 places the field so that the entire cervical spine is captured within the image margins, ensuring the C7–T1 junction is included without clipping. This combination—full cranial-to-upper thoracic coverage, minimized shoulder overlap, and a central point around C4—provides the most reliable view of the critical junction for assessment. Centering near the pelvis or near the skull base without addressing shoulder overlap, or twisting the head, would either miss the junction or distort the anatomy.
