What is this test?

Spinal MRI is an imaging test that uses magnetic fields and radio waves to create detailed pictures of the spine. This examination may include images taken without contrast and again after an IV contrast medicine, often gadolinium, is given.

Why might I need this test?

A spinal MRI may be ordered to investigate back or neck pain, numbness, weakness, trauma, or symptoms suggesting pressure on the spinal cord or nerves. It can also help evaluate discs, bones, spinal tumors, infections, or inflammatory conditions.

How is the test performed?

You will lie on a table that moves into the MRI scanner. The technologist will guide you and may ask you to remain still. If contrast is included, it is usually injected through an IV line in your arm.

How do I prepare for the test?

Follow the imaging center's instructions about medications, fasting, and IV contrast. Tell the staff if you have a metal implant, severe kidney disease, previous contrast reaction, or possible pregnancy, because these factors may affect the examination.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does the spinal MRI involve radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation.
Why might I need both noncontrast and contrast images?
Noncontrast images show the basic structure of the spine, while contrast may make inflammation, infection, tumors, or other abnormalities easier to evaluate.
Is IV contrast safe for everyone?
Most people tolerate it well, but kidney disease or a prior serious reaction can increase risk. Tell the imaging team about these conditions before the examination.
