In addition to X-rays, these other tests may be used to diagnose spinal stenosis:
Magnetic resonance imaging (MRI) scans are the best tools for diagnosing stenosis. An MRI uses magnetic
fields and radio-frequency waves to create an image of the spine, and
can reveal the details of the spinal canal. An MRI scan can also show
evidence of previous injuries that may have healed and other details in
the spine that can’t normally be seen on an x-ray.
Myelogram: This special x-ray uses dye, which is injected into the spinal fluid.
This can identify spinal stenosis. Usually a CT scan follows the myelogram.
Computerized tomography (CT) is a noninvasive procedure that uses x-rays to produce a three-dimensional
image of the spine and identify spinal stenosis.
Electromyogram and Nerve Conduction Studies (EMG/NCS): This test measures the electrical activity in the nerves and muscles.
It may identify if there is nerve damage or nerve compression.
At the Weill Cornell Brain and Spine Center, our specialists have advanced
training in treating conditions of the spine. We can also provide second
opinions on a diagnosis. (See
