Bone Density vs. Bone Quality | Osteoporosis Screening Chandler AZ

Watch Dr. Krishnan explain it in under 2 minutes:

If you or someone you love has been told "you have osteoporosis" or "you have osteopenia," there is one question worth asking before any decision is made:

"Can we look at my bone quality, not just my bone density?"

What a standard DEXA actually measures

A standard X-ray DEXA scan measures bone mineral density, which is how much mineralized bone you have. Your result is reported as a T-score, which compares you to the average healthy 30-year-old. The World Health Organization uses T-score cut-offs to define osteopenia and osteoporosis.

What a DEXA does not tell us is how that bone is arranged inside. That internal structure is called microarchitecture, and it is what we mean by bone quality.

Why quantity and quality are different things

Think about sound. We can describe how loud a sound is, but that doesn't tell us whether we're hearing a guitar, a flute, or a drum. Loudness is quantity. The character of the sound is quality.

Bones work the same way. Two people can have the same amount of bone, yet one has a dense, well-connected internal framework and the other has gaps and thin, widely spaced supports. Ultrasound-based bone quality assessment helps tell these apart: normal quality, decreased quality with some gaps, or low quality with larger gaps, which is the pattern of truly porous bone.

Why petite women are often caught by density-only testing

Because the T-score is compared with an average, women who are naturally small-framed can score low on the amount of bone simply because they are small and don't need to build as much.

An example. Consider a patient who weighs 110 pounds and has a T-score of −3.6. By WHO criteria, that is osteoporosis. But when we assessed her bone quality, her fragility score was in the green, meaning normal quality bone. That is not the picture of porous bone.

If we relied only on density, she would likely have been told she needs medication right now. With bone quality information as well, she can have a shared decision-making conversation with her own provider about whether medication is needed at all, or whether other approaches make more sense.

This matters because osteoporosis medications have side effects, and the benefits should always outweigh the risks. Bone quality is one more piece of information to help you and your provider decide, not a replacement for your provider's judgment.

R.E.M.S Echolight bone density and bone quality ultrasound at URPrecious

At URPrecious Imaging, we offer R.E.M.S Echolight, a radiation-free ultrasound test that assesses both bone density and bone quality. We check the lumbar spine and both femoral necks, the same key areas that matter for fracture risk.

Insurance: This test is often covered as an office visit through your insurance, though coverage varies by plan.
Self-pay: Regularly $250, but $149 through the end of December as part of our wellness screening special.
Save more with a bundle: Add it to a screening breast ultrasound or whole body ultrasound. Our Breast & Bone Wellness Package is $299.

Appointments for special-priced packages must be completed by December 23, 2026. Our office is closed December 24–31.

Who should consider bone quality testing?

Women who have been told they have osteopenia or osteoporosis and want a fuller picture before deciding on treatment
Petite or small-framed women whose density scores may not reflect their true bone structure
Anyone considering osteoporosis medication who wants more information for a shared decision with their provider
Women in the pre- or perimenopausal years who want to begin looking after their bones early

Please don't wait until 65

Many women first think about bone health around age 65. We'd encourage starting sooner. Beginning in the pre- or perimenopausal years gives you time to make gradual, sustainable changes in nutrition, movement, and lifestyle, and to talk with your provider about your options, so that you aren't facing drastic lifestyle changes or medications all at once.

Frequently asked questions

Does bone quality testing replace a DEXA? No. A DEXA remains a standard test and your provider may still want one. Bone quality adds information about microarchitecture that density alone does not provide. Please discuss which tests are right for you with your own provider.

Is R.E.M.S Echolight safe? It is ultrasound-based and does not use ionizing radiation.

Do I need a referral? No referral is needed to book our self-pay wellness packages.

Should I stop or change my medication based on this test? Please don't make any medication changes on your own. Bring your results to your provider and make decisions together.
