After a fall or road accident, CT scan of the neck spine checks for fractures and instability. Learn when it is needed, why the neck is protected and what the scan shows.
CT scan of the cervical spine is the main test to find fractures after a neck injury, such as in road accidents or falls. It shows broken bones, dislocations and unstable injuries in minutes. MRI is added when nerve or spinal cord injury, ligament tears or disc injury are suspected. A neck collar is kept on until the spine is cleared by a doctor.
Who Needs a CT of the Neck After Injury?
- High-impact accidents and falls from height
- Neck pain with tenderness over the spine
- Weakness, numbness or tingling in the arms or legs
- Reduced consciousness or intoxication
- Age above 65 with neck trauma
- Other serious injuries
Doctors use rules such as NEXUS or Canadian C-spine rules to decide. See whole body trauma CT.
What CT Shows
CT shows the seven neck bones (C1 to C7), their alignment, fractures, fragments pressing into the spinal canal and joint dislocations. Sagittal and coronal images are made from the same scan. It is quick, which helps in emergencies. See CT spine scan and 3D CT for fractures.

If CT is normal but there are neurological symptoms, severe pain or the patient cannot be examined, MRI checks ligaments, discs, cord bruising and bleeding. Some centres do MRI in all with unexplained weakness. See MRI cervical spine and MRI for spinal cord compression.
First Aid for Suspected Neck Injury
- Do not move the person unless in danger.
- Keep the head and neck in line, using hands on both sides of the head.
- Call emergency services.
- Do not remove a helmet unless trained.
Preparation and Safety
In emergencies, there is no preparation. The patient stays in the collar and is moved with care. Contrast is rarely needed unless an artery injury is suspected. CT uses radiation, but the benefit is high when a serious injury is possible. See CT scan radiation dose.
A Practical Example
Vijay, 32, is thrown off a bike and has severe neck pain. CT shows a fracture of C6 with a small fragment near the canal, and he is placed in traction and operated on the same day. A friend with a similar fall has a normal CT and only a muscle strain, so the collar is removed after examination.
After the Scan and Next Steps
Take the CT and MRI reports to a spine surgeon. Treatment may be a collar or brace, traction or surgery, followed by physiotherapy. Do not lift heavy weights, avoid rapid neck movements, and report any weakness, numbness, balance problems or bladder changes at once.
Questions to Ask Your Doctor
- Is my neck bone fractured or unstable?
- Do I need MRI as well?
- How long should I wear a collar?
- When can I return to work and sport?
Common Mistakes to Avoid
- Moving an injured person's neck unnecessarily.
- Removing the collar before clearance.
- Ignoring tingling or weakness after injury.
Booking, Timing and Report
Most CT scans can be booked on the same day, and the visit takes 20 to 40 minutes. Carry your prescription, old scans and a recent creatinine report if contrast is planned. Reports are usually ready within 24 hours, and images can be provided on a CD or digital link for your doctor.
Key Facts at a Glance
- Keep the neck in line and wait for help after a serious injury
- CT is the first test for fractures
- MRI shows ligament and spinal cord injury
- Do not remove the collar until cleared
Recovery and Neck Care Tips
After a neck injury is cleared or treated, sleep with a supportive pillow, avoid sudden twisting and heavy loads, and follow physiotherapy exercises to rebuild strength gradually. Apply warmth for muscle spasm after the first few days, if advised. Return to driving and sport only when your doctor agrees and you can turn your head comfortably.
