What is this test?

Spinal MRI with intravenous contrast is an imaging test that uses a magnetic field, radiofrequency signals, and a contrast material given through a vein to produce detailed pictures of the spine.

Why might I need this test?

Your clinician may order this test to investigate persistent back or neck pain, numbness, weakness, problems with bladder or bowel function, spinal trauma, or symptoms that may involve the spinal cord or nerves.

How is the test performed?

You will lie on a table that moves into the MRI scanner. Images are taken while you remain still, and an IV contrast agent may be injected during the examination. The test does not use ionizing radiation.

How do I prepare for the test?

Follow the instructions provided by the imaging center, including whether to avoid eating or drinking beforehand. Tell the care team about metal implants, prior reactions to contrast, kidney problems, and pregnancy or possible pregnancy.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does a spinal MRI with contrast use radiation?
No. MRI uses magnetic fields and radiofrequency signals rather than ionizing radiation, although the injected contrast material is a medication.
Why is contrast used for a spinal MRI?
Contrast may make certain tissues, inflammation, infection, or masses easier to distinguish. It is not needed for every spinal MRI and is used only when clinically appropriate.
Will I need to have blood drawn before the test?
Sometimes. The imaging center may check kidney function or contrast allergy information before giving IV contrast, depending on its policies and your medical history.
