COVID-19 restrictions to remain in place at The Walton Centre

Restrictions remain in place across the NHS in relation to the COVID-19 pandemic. The safety measures in place over the 18 months therefore remain in place at The Walton Centre - and in our other clinic settings within the community – until further notice.

Due to the increased transmission risk posed by the Omicron variant, visiting has been suspended within The Walton Centre except for exceptional circumstances.


Service contact information

Service detail

The fluoroscopy suite uses live X-ray pictures to aid the practitioner performing certain procedures. These commonly include lumbar punctures, myelograms and video fluoroscopy swallows.


What is a myelogram?

  • A lumbar puncture is performed under x-ray guidance
  • Once the needle is in position, X-ray dye (Omnipaque 300) is injected into the spinal fluid
  • X-ray pictures, followed by a CT scan, are used to look at the spine

How is it done?

  • Usually you will be admitted to a day ward
  • You will be lying on your left side, on an X-ray table
  • Using X-rays, a fine needle is placed in your lower back
  • A small sample of spinal fluid is taken for testing and a small amount of X-ray dye is injected into the spinal fluid
  • You will then be asked to turn over in various directions
  • This is to help move the dye around the curves of your spine
  • X-ray pictures will be taken with you in various positions
  • Finally, you will be transferred to have a CT scan.

How long does it take?

The procedure takes approximately 20-30 minutes.

What are the risks?

Half the people who have a myelogram get a headache afterwards, which can last a few days. Drinking plenty of fluids, and taking painkillers or drinks containing caffeine can help (tea, coffee, cola, etc.). Some people find their symptoms get worse for a few days. However, this should be temporary.
