What is this test?
A spine MRI uses magnetic fields and radio waves to create detailed pictures of the spine. It can assess the vertebrae, spinal discs, spinal cord, nerve roots, and nearby soft tissues. This test is performed without intravenous contrast.
Why might I need this test?
A spine MRI may be ordered to investigate back or neck pain, numbness, weakness, trauma, or suspected nerve compression. It can also help identify disc disease, spinal stenosis, tumors, infections, or changes in the spinal cord.
How is the test performed?
You will lie on a table that moves into a large MRI scanner. The scanner makes loud knocking and clicking sounds while it takes images. A technician may ask you to remain still, and the scan usually takes 20 to 60 minutes, depending on the area and sequences needed.
How do I prepare for the test?
Follow the instructions provided by the imaging center. Fasting is generally not required for a spine MRI without contrast. Remove jewelry, watches, hairpins, and other metal objects, and tell the staff about any implanted devices, medication patches, pregnancy possibility, or inability to lie still.
