A DEXA scan, also called a DXA scan or bone density test, is an imaging test that measures bone mineral density or bone strength. It helps doctors assess your risk for fractures and diagnose osteoporosis, osteopenia and other bone diseases.

Doctors use DEXA scans (which stands for dual energy X-ray absorptiometry) to evaluate your bone health. You may need a bone density test if you are:

Bone density tests give doctors information they need to make the best possible care decisions. Results can help:

Tell how well a treatment is working

Expertise in bone density tests for adults and children in central Missouri

Advanced equipment and expertise are critical for the getting most accurate results from imaging tests.

DEXA scans look at minerals in your bones. Bone minerals are what give bones strength. Generally, the higher the bone minerals, the denser — and stronger — the bone.

Doctors use bone density tests to diagnose weak bones and certain diseases that affect your bones like osteoporosis and osteopenia.

Osteopenia is low bone mineral density. People with low bone mineral density have an increased risk for bone fractures and this can progress to osteoporosis.  

Osteoporosis is a condition that causes the bones to become porous, weak and more susceptible to fracture. It happens when bone loss occurs at a rate that’s faster than new bone can replace it. 

 While both men and women can have osteoporosis, it’s more common in women after menopause. The risk is also higher for those with a family history of osteoporosis, tobacco use, heavy alcohol use, and chronic steroid use. There are several other medical conditions and medications that increase your risk of bone loss leading to osteoporosis such as diabetes, rheumatoid arthritis, antidepressant medications, and proton pump inhibitors.

Certain factors increase your risk for osteopenia and osteoporosis, including:

Medications like steroids, hormone therapy for cancer and anti-seizure medicines

A DEXA scan is painless. It’s noninvasive and it only takes a few minutes.

The MU Health Care imaging team will answer your questions and help you feel comfortable throughout the test. 

Here’s what you can expect:

Your T-score is a number that indicates your bone mass:

Our radiologists will send the results to your referring doctor as soon as possible. Your doctor will let you know the results and recommend treatment, if needed.

You can see your DEXA scan results online using our patient portal about seven days after your appointment.
