What is a spine MRI exam?
Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to produce clear, detailed images of your internal organs, tissues, and joints. A spine MRI provides images of your spinal cord, vertebrae, and the spaces between the vertebrae.
Why has my physician ordered this exam?
Your physician may call for a spine MRI to diagnose and assess a condition, help plan spine surgery, or monitor postsurgical changes.
A presurgical spine MRI can help evaluate the presence of:
- Issues with an intervertebral disk: bulging, degeneration, or hernia
If there is a lack of improvement after spine surgery, a postsurgical spine MRI can help your physician determine a cause.
What might prevent my physician from ordering this exam?
Some metals interfere with MRI equipment. Be certain your physician knows if you have:
- Aneurysm clips
- Implanted neurostimulator
- Inner-ear implants
- Metal fragments in your eye(s)
- Pacing wires
- Transcutaneous electrical nerve stimulation (TENS) unit
