What is this test?
Cervical spine MRI is a noninvasive imaging test that uses magnetic fields and radio waves to produce detailed pictures of the neck and upper spinal cord. It is performed without injected contrast.
Why might I need this test?
Your clinician may order this test to investigate neck pain, numbness, weakness, tingling, or symptoms that could be related to pressure on the spinal cord or nerves. It may also be used to assess injuries, abnormal spinal alignment, or other structural changes.
How is the test performed?
You will lie on a table that moves into a large MRI scanner. The scanner makes loud knocking and ringing sounds, and you may be asked to remain still. Because this examination is performed without contrast, no contrast dye is injected.
How do I prepare for the test?
Follow the imaging center's instructions and tell the staff about any metal implants, medication patches, pregnancy, or previous problems with MRI scanners. Remove jewelry, hairpins, watches, and other metal objects before the examination. Fasting is generally not required unless specifically requested.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate cervical disc disease, narrowing of the spinal canal, pressure on the spinal cord or nerves, vertebral injury, or other structural problems. The significance depends on the symptoms, medical history, and the full imaging report. A radiologist or your clinician should explain any findings in the context of your condition.
