Magnetic Resonance Imaging (MRI)
An MRI uses magnetic fields and radio-frequency waves to create an image of the spine and can reveal fine details of the spine, including tumors, nerves, and any damage to the spine. An MRI scan can show details in the spine that can’t normally be seen on an x-ray. Sometimes a contrast agent is injected into a vein in the hand or arm during the test, which highlights certain tissues and structures to make details even clearer. In cases of radiculopathy, the affected nerves will be revealed.
