An axial or central DEXA (Dual Energy X-ray Absorbtiometry) scan is a fast, accurate way of assessing bone density. DEXA uses low energy X-rays to help determine if you have osteoporosis or are at risk of developing osteoporosis.
A diagnosis of osteoporosis is essential to prevent life threatening fractures in high risk individuals. DEXA scans can also detect bone-related conditions, such as osteopenia.
Based at East Surrey Hospital, the DEXA service is and is provided by a senior radiographer supported by a team of skilled radiographers with specialist training. A report of the DEXA scan is made within seven working days by either a consultant radiologist or consultant rheumatologist.
DEXA scanning is provided by appointment only.
Please note the DEXA service currently has a waiting time of around two weeks.
To book a DEXA scan, or for more information, please contact: Alain Carmen at Alain.
We’re pleased to let you know that a DXA scanning service is now available at East Surrey Hospital for children and adolescents aged 11 to 17.
This will help reduce the need for some young patients to travel to St George’s Hospital for their scan.
Please note: a DXA scan should only be requested if the results will directly influence clinical management. Most referrals are expected to come from specialist services, with the patient’s GP asked to arrange a local scan.
There are some limitations to the service:
-
We are unable to scan non-ambulant children or adolescents, as interpretation in cases of abnormal bone development requires specialist expertise.
-
A scan cannot be performed if the child cannot be safely and appropriately positioned.
If you have any questions about this service, please contact a member of the team:
Dr Sian Griffith, Consultant Rheumatologist and Osteoporosis Lead Consultant
Alain Joy Carmen-Marley, DXA Superintendent, East Surrey Hospital
How long is the scan?
The scan takes 15-30 minutes.
What is the scan like?
During the scan you will lie on your back on a flat and open X-ray table. A scanning arm will pass over your body to complete the scan.
Why do I need a DEXA scan?
Having certain osteoporosis risk factors means you may need a DEXA scan. Risks factors include:
- Breaking bones easily
- Long term glucocorticoids (steroids)
- A parent with a a hip fracture
- Early menopause (before 45) without HRT
- Rheumatoid arthritis
If you think you might be at risk of osteoporosis, please speak to your GP.
Can I have a DEXA scan if I'm pregnant?
Although the radiation dose received during a DEXA scan is extremely low, this type of scan is not recommended for pregnant patients.
