Tests and diagnosis

By Mayo Clinic staff

To diagnose syringomyelia, your doctor will begin by asking about your medical history and doing a complete physical examination.

If your doctor suspects syringomyelia, you'll likely undergo a magnetic resonance imaging (MRI) scan of your spine and spinal cord. An MRI is the most reliable tool for diagnosing syringomyelia.

Using magnetic fields and radio waves, an MRI produces 3-D, high-resolution images of your spine and spinal cord. If a syrinx has developed within your spinal cord, your doctor will be able to see it on an MRI. A dye or contrast medium can be injected for the test, and once it travels to your spine, it can enhance the MRI images. An MRI is a safe and painless test. Over time, repeat MRIs can be used to monitor the progression of syringomyelia.

In some cases, syringomyelia may be discovered incidentally when a spine MRI or computerized tomography (CT) scan is done for other reasons.
