What is this test?

A cervical spine CT is a computed tomography scan that creates detailed X-ray images of the seven vertebrae in the neck. The scan is performed without intravenous contrast dye.

Why might I need this test?

Your clinician may order this test to evaluate neck pain, a traumatic injury, or symptoms that could involve the cervical spinal cord or nerves. It may also be used to assess bone abnormalities, infection, or a suspected mass.

How is the test performed?

You will lie on a CT table while an X-ray machine rotates around your neck to take multiple images. The procedure is generally painless and usually takes only a few minutes, although the entire visit may take longer.

How do I prepare for the test?

No special preparation is usually required for a CT scan without contrast. You may be asked to remove jewelry, hairpins, hearing aids, and metal items from around your neck. Tell the imaging staff if you are pregnant or may be pregnant.

Frequently asked questions

Does this CT scan use contrast dye?
No. This version of the cervical spine CT is performed without intravenous contrast. Tell the care team if you have had an allergic reaction to contrast, although contrast is not being used for this test.
Is a cervical spine CT the same as a neck ultrasound?
No. CT uses X-rays to create cross-sectional images of the cervical vertebrae and surrounding tissues, while ultrasound uses sound waves and is not typically used to evaluate the cervical spine in this way.
Will I need someone to drive me home?
Usually not, because this scan does not involve sedation or contrast. You can generally drive yourself unless you received sedating medication, have a condition that makes travel unsafe, or your clinician has given you specific restrictions.
