Neck Trauma or Neurological Emergency — Go to ER
Acute neck injury after trauma, rapidly progressive arm or leg weakness, sudden loss of bowel or bladder control, or any acute change in neurological function requires emergency evaluation. Call 911 or go to the nearest ER. DOD is not for emergencies.
Cervical Spine MRI: What Patients Should Know
A cervical spine MRI uses magnetic resonance imaging to create detailed images of the neck — including the seven cervical vertebrae (C1–C7), the intervertebral discs, the cervical spinal cord, and the nerve roots that exit at each level. It does not use ionizing radiation.

Quick Answer
A cervical spine MRI images the seven cervical vertebrae (C1–C7), intervertebral discs, spinal cord, nerve roots, and neural foramina using magnetic fields and radio waves. No ionizing radiation is involved. Provider orders are required at most facilities. DOD can review cervical spine MRI order requests for eligible patients in supported states. Acute trauma or rapidly progressive neurological symptoms require emergency evaluation — not an MRI order.
Cervical Spine Anatomy on MRI
The cervical spine consists of seven vertebrae (C1–C7) supporting the neck and protecting the cervical spinal cord. C1 (atlas) and C2 (axis) have unique anatomy that allows head rotation. The remaining cervical levels (C3–C7) each have an intervertebral disc and neural foramina through which nerve roots exit bilaterally. The cervical spinal cord passes through the cervical canal from the foramen magnum at the base of the skull.
Cervical spine MRI can visualize vertebral body alignment, disc height and signal, central canal size, foraminal width, spinal cord morphology and signal characteristics, and paraspinal soft tissues. According to RadiologyInfo.org, MRI is the preferred modality for detailed soft tissue evaluation of the cervical spine.
