Which vertebral levels should be included on a standard cervical spine series?

• A. Occipital bone through T1
• B. From C2 to C6
• C. From skull base to C5
• D. From C1 through T3

Answer: (A)

When imaging the cervical spine, you want to visualize from the base of the skull down to the first thoracic vertebra. This range ensures that C1 through C7 and the cervicothoracic junction are fully captured, which is essential for assessing alignment, fractures, and degenerative changes across the entire cervical region. The skull base is the upper boundary so injuries at C1–C2 and the odontoid area can be seen, while ending at T1 allows the lower cervical vertebrae and the C7–T1 articulation to be evaluated. If the field stops higher, you risk missing injuries at the lower cervical levels or misjudging alignment at the cervicothoracic transition.
