Facts About Bone Density (DEXA Scan)
The basics
DEXA (dual x-ray absorptiometry) is important for diagnosing (seeing if someone has) osteoporosis or bone thinning.
The amount of radiation used in DEXA scans is very low and similar to the amount of radiation used in x-rays.
We are all exposed to ionizing radiation every day from the natural environment. However, added exposures can slightly increase the risk of developing cancer later in life.
What you should know
Your healthcare provider may recommend a DEXA scan to test for osteoporosis or thinning of your bones.
Screening for osteoporosis is recommended for women who are 65 years old or older and for women who are 50 to 64 and have certain risk factors, such as having a parent who has broken a hip.
However, there are other risk factors for osteoporosis besides age and sex, such as some intestinal disorders, multiple sclerosis, or low body weight.
