A bone density scan for osteoporosis - the condition of having fragile bones - is a painless and simple form of X-ray called a DEXA (dual energy X-ray absorptiometry). It measures possible bone loss.
DEXA scans look for signs of fragile bones and help assess your risk of developing fractures, while also sometimes being used to monitor the effects of treatment for osteoporosis.
A referral letter from a consultant or GP is required before booking any diagnostic investigation.
Osteoporosis affects men and women of all ages, but is more common in older post-menopausal women because their oestrogen declines after the menopause, resulting in a decrease in bone density. If you are female, you might be advised to have a DEXA scan if you:
If you are male, you might be advised to have a scan if you have:

A DEXA scan is a very safe, quick and painless procedure but isn’t suitable for pregnant women due to the level of radiation.
Having this scan can identify the problem before it becomes worse so treatment can begin quickly.
DEXA scans are carried out as an outpatient procedure in the imaging or radiology department and usually take 10 to 15 minutes. You will be awake during the procedure but will also have to stay still.

DEXA scans are routinely done as an outpatient procedure in the imaging or radiology department. You will be asked to lie down on an X-ray table for 10-15 minutes while the machine’s scanning arm passes over you to take an image of the relevant area of your body. This will often be your spine or your hip. (source: National Osteoporosis Society). It’s important to lie very still during the test. The information is then sent to a computer for your doctor to study.
The dose of radiation used during a DEXA scan is much lower than that used during a normal X-ray so the risks are much lower.
You won’t need to be inside a tunnel or a ring for this procedure. You won’t even need to remove any clothing except metal fasteners, such as zips, hooks or buckles, and jewellery.
This is a relatively straightforward test and you can go straight home afterwards or as soon as you feel comfortable.
Your radiologist will study the scans taken, prepare a report and send the results to your doctor, which should take a few days. The results of the scan are given as a T-score between 0 to -2.5 and measures how your bone density compares with that of the normal average for healthy adults of your age, gender and ethnicity.
Even once you’ve left hospital, we’re still here for you. Your consultant is likely to want to see you after your scan, a follow up appointment will be made for you before you leave the hospital.
Your doctor will have looked at your results and if your T-score is low, this could mean that your bones are fragile and therefore more likely to fracture. They will suggest treatment options and discuss with you if you need more tests.
We take an integrated approach so we can organise any other care that you may need should your test results show you have osteoporosis.
