Which are key criteria for a diagnostic lateral cervical spine radiograph?

• A. Vertebral bodies Titanic; spinous processes misaligned; skull base included
• B. Vertebral bodies superimposed; spinous processes aligned; skull base to T1 included; no rotation
• C. No rotation; only C1–C3 included
• D. Cropping to exclude skull base

Answer: (B)

For a diagnostic lateral cervical spine radiograph, the projection must be a true lateral with no rotation and include the entire cervical spine from the skull base down to the upper thoracic junction. The key signs are vertebral bodies that are superimposed evenly and spinous processes that are aligned in a straight line. Including the skull base through the T1 level is essential so you can assess the full extent of the cervical column and verify proper alignment at the upper spine, while also ensuring you don’t miss injuries or misalignment at the craniocervical junction. If the skull base is cropped out, you can’t confirm a true lateral or assess basilar region and occipitocervical alignment, which compromises the study. Likewise, omitting any part of the cervical spine (for example stopping at C3) leaves the rest of the column unseen and could miss instability or fractures. And if there’s rotation, the vertebral bodies won’t appear evenly superimposed and the spinous processes won’t lie in a straight line, making the radiograph unreliable for assessment. So the best choice describes a true lateral view with vertebral bodies superimposed, spinous processes aligned, full inclusion from skull base to T1, and no rotation.
