What is this test?

This is an MRI examination of the entire spine. Images are first obtained without contrast and then repeated after a gadolinium-based contrast agent is injected into a vein.

Why might I need this test?

An entire-spine MRI may be used to investigate back or neck pain, numbness, weakness, walking problems, or symptoms suggesting nerve or spinal cord involvement. It can also assess the spread of tumors, infection, inflammation, or other disease.

How is the test performed?

You will lie on a table that moves you through a large MRI scanner. The scan generally requires you to remain still, and the technologist may ask you to hold your breath briefly during image collection.

How do I prepare for the test?

Tell the imaging team about any metal implants, pacemaker or other implanted devices, prior contrast reactions, kidney disease, and possible pregnancy. Follow the facility's instructions about eating, drinking, and taking medications.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include disc disease, spinal canal narrowing, vertebral compression, bone lesions, infection, inflammation, cysts, or spinal cord abnormalities. Comparing images before and after contrast can help show which areas enhance, which may guide further evaluation or treatment.

Frequently asked questions

Will I receive contrast during the scan?
Yes. This examination includes images before and after an IV contrast injection, unless the imaging team determines that contrast cannot be safely administered.
Is the MRI painful?
The MRI itself is generally painless. The IV contrast injection may briefly cause a sensation of warmth, a metallic taste, or discomfort at the injection site.
How long does the examination take?
The exact time varies by facility and the extent of imaging needed. You should ask the imaging center for an estimated appointment duration and whether you need someone to drive you home.
