Bone density scanning or dual-energy x-ray absorptiometry (DEXA) is a type
of low-dose x-ray test that measures calcium and other minerals in your
bones. This test is most often used to diagnose osteoporosis—a condition
that often affects women after menopause, but can also be found in men.
Osteoporosis involves a gradual loss of calcium, causing the bones to
become thinner, more fragile, and more likely to break.
Bone density scanning can also assess your risk for developing fractures.
If your bone density is found to be low, you and your physician can work
together to develop a treatment plan designed to help prevent fractures
before they occur. This scan is also effective in tracking the effects
of treatment for osteoporosis or for other conditions that cause bone loss.
Why might I need a bone density test?
Bone density testing is strongly recommended if you:
Are a post-menopausal woman and not taking estrogen
Have a personal or maternal history of hip fracture or smoking
Are a post-menopausal woman who is tall (over 5’ 7”) or thin
(less than 125 pounds)
Use medications that are known to cause bone loss, including corticosteroids
such as Prednisone, various anti-seizure medications such as Dilantin
and certain barbiturates, or high-dose thyroid replacement drugs.
Have Type 1 diabetes—formerly called juvenile or insulin-dependent
diabetes, liver disease, kidney disease, or a family history of osteoporosis
Have high bone turnover, which shows up in the form of excessive collagen
in urine samples
Have a thyroid condition, such as hyperthyroidism
Have experienced a fracture after only mild trauma
Have had X-ray evidence of vertebral fracture or other signs of osteoporosis
How is a bone density scan performed?
A bone density scan is a quick and painless procedure that involves lying
on your back on an x-ray table so an area of your body can be scanned.
You may be able to remain fully clothed, depending on the area of your
body being scanned. However, you will need to remove any clothes that
have metal fasteners, such as zips, hooks, buckles or buttons.
How often should a bone density test be done?
Medicare allows a bone density scan to be done once every two years, and
this is the current recommended timeframe. There are exceptions to this
rule if you have certain diseases.
Your healthcare provider will consider several factors, such as your age,
level of fracture risk, previous medical history and current medications.
Your healthcare provider will then make a personalized plan for how to
assess and protect your bone health.
