Fluoroscopy

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.
