Magnetic Resonance Imaging of the Spine With and Without Intravenous Contrast
An MRI scan of the spine, often performed before and after intravenous contrast, to evaluate the vertebrae, discs, spinal cord, and surrounding tissues.
["This imaging test uses magnetic fields and sometimes intravenous contrast to evaluate abnormalities in the spine."]

What is this test?
Spinal magnetic resonance imaging (MRI) creates detailed pictures of the spine using magnetic fields and radio waves. Depending on the protocol, images may be taken before and after an intravenous contrast injection is given.
Why might I need this test?
This test may be ordered to investigate back or neck pain, numbness, weakness, trouble walking, trauma, or symptoms suggesting pressure on the spinal cord. It can help evaluate the vertebrae, spinal discs, spinal cord, nerves, and surrounding soft tissues.
How is the test performed?
You will usually lie on a table inside the MRI scanner. The technologist may position you to obtain images of the requested area of the spine, and you may be given contrast through a small intravenous catheter. You will be asked to remain still and may be given instructions about holding your breath.
How do I prepare for the test?
Tell the imaging team if you have metal implants, a pacemaker or other implanted device, a history of contrast allergy, kidney disease, or any chance of pregnancy. Follow the center's instructions, remove loose metal objects, and arrive early to complete safety screening and consent.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate problems such as disc disease, spinal stenosis, vertebral injury, infection, inflammation, cysts, or a mass affecting the spinal cord or nerves. The results should be interpreted by a radiologist together with your symptoms, examination, and other tests because abnormal-looking areas do not always represent the cause of a person's symptoms.
