It measures density, not fragility
Two women with the same T-score can carry very different fracture risk. DEXA has no way to tell them apart, because it was never designed to assess how bone is put together.
Echolight REMS · A plain-language guide Your T-score is important. But it is not the whole story.
A T-score tells you how dense your bones are. It does not tell you how fragile they are. Echolight REMS measures density at the spine and hip and adds a Fragility Score, so you finally see both halves of the picture.
No radiation. No referral. Your results explained the same day.
What your DEXA cannot tell you
Most women who break a bone were told they did not have osteoporosis.
In a U.S. study of nearly 150,000 postmenopausal women, 82% of those who fractured in the following year had a T-score better than -2.5. Their density looked acceptable. Their bones broke anyway.
That is the gap in a density test. DEXA counts how much mineral is in your bone. It says nothing about how that bone is built, and structure is what decides whether a bone holds or breaks.
82%
of women who fractured had a T-score above the osteoporosis line.

Your spine reading can flatter you
DEXA is an X-ray shadow. Arthritis in the spine, a calcified artery, or an old compressed vertebra all block X-rays and get counted as extra bone. The result is a spine score that looks stronger than the bone is. Others with scoliosis or a twisting spine can artificially show dramatically lower bone density.
You wait two years, then get six minutes
Insurance usually covers a DEXA every two years. A different machine or a slightly different position on the table can shift your number by a few percent. Then the report arrives with a T-score and very little explanation.
What REMS adds
The same T-score, plus the answer DEXA cannot give you.
REMS (Radiofrequency Echographic Multi Spectrometry) reads the ultrasound signal coming back from inside your lumbar spine and hip, the same two sites a DEXA examines. From that signal it reports a T-score on the scale your doctor already uses, and something most DEXA reports have no equivalent for: a Fragility Score.
This is not the heel test from the pharmacy. That looks at one bone in the foot. REMS examines the bones where fractures do the most damage.
A Fragility Score tied to real fractures
The Fragility Score estimates how fragile your bone is, separately from its density. A five-year study published in 2026 followed patients after their REMS scans: the higher the fragility class, the more fractures followed. It is an estimate drawn from the ultrasound signal, not a photograph of your bone, and it is the first number most women have ever seen on this half of the picture.
Built to read bone, not what surrounds it
REMS analysis is designed to recognise signals that do not come from healthy bone tissue, such as calcifications and arthritic growths, and leave them out. If spine arthritis has been muddying your DEXA, this is the second look worth having. If you have spinal curvature, the REMS does not get confused and may provide more accurate results.
No radiation, no referral, no waiting
REMS uses sound waves, so there is no X-ray dose at all. DEXA radiation is very low, so this is about freedom, not fear: you can be scanned when you have a question, without a prescription and without waiting for an insurance clock.
Answers in the same visit
Your results are ready minutes after the scan. Ray Hinish, PharmD, sets aside 30 to 60 minutes to go through them with you. You leave understanding your numbers, not searching the internet for what they mean.
What each scan tells you.
| DEXA | Echolight REMS | |
|---|---|---|
| Bone density (T-score) | Yes | Yes, at the spine and hip |
| Bone fragility | Not assessed | Fragility Score |
| Spine arthritis and calcification | Can inflate the reading | Designed to filter them out |
| Radiation | Very low dose X-ray | None |
| Referral | Usually required | Not needed |
| Results explained | Often days later, in a short visit | Same visit, 45 to 60 minutes |
| Used by insurers and for prescriptions | Yes, the standard | Not yet routine |
Can I trust it?
This is a medical device with published research behind it.
FDA-cleared
The Echolight EchoS device family received FDA 510(k) clearance in 2021.
17 studies
A 2026 review pooled 17 studies and found strong agreement, on average, between REMS and DEXA density results. Individual studies varied.
5 years
A prospective study tracked patients for five years and linked their REMS fragility class to the fractures that followed.
“If it were this good, every hospital would have one.”
Medicine adopts new tools slowly. Guidelines, equipment budgets, and insurance payment all lag behind the research, often by years. The International Society for Clinical Densitometry has put REMS on the agenda for formal review at its 2027 position conference. You do not have to wait for that to finish to use it. NASA has already started using the REMS scan in their astronauts.
“My doctor never mentioned it.”
Most doctors order the test their training and your insurance are built around, and that is DEXA. Silence about REMS usually means it is not in their workflow, not that they weighed it and said no. You can get the scan, bring the report, and give your doctor more to work with. The published research is available in the databases your doctor uses to research treatments and tests.

Before you decide
The five things that hold women back.
“I already have a diagnosis. What would this change?”
A diagnosis tells you which category you are in. It does not tell you how fragile your bones are within it, or where to put your effort. That is what a Fragility Score and an hour of explanation are for.
“I’ll lose years of DEXA history.”
You keep all of it. REMS starts its own baseline beside your DEXA record. Compare REMS with REMS and DEXA with DEXA, and you have two views of your bones where you used to have one. The extra information provided by the Fragility Score is a powerful addition to your testing.
“Insurance doesn’t cover it, so it can’t be necessary.”
Insurance decides what it pays for. It does not decide what is worth knowing. The fee is $300, stated up front, and it covers the scan, all three reports, and up to an hour with Dr. Ray Hinish.
“This will push me toward medication.”
It will not. A scan gives you information, and nobody here prescribes anything. Medication decisions stay with you and your doctor. Most women leave with a clearer view and a lifestyle plan they can start that week whether they choose to pursue medications or not.
“I don’t want another test that scares me.”
The fear rarely comes from the number. It comes from not knowing what the number means or whether anything you are doing helps. A fuller picture either shows your bones are sturdier than your T-score implied, or shows you exactly where to aim. Both are easier to live with than a question mark.
From women who have had the scan
What they said afterwards.
Is it right for me?
REMS is the right next scan if you:
- Have a T-score and no idea how fragile your bones are.
- Have spine arthritis, or a spine score that does not match your hip.
- Got a DEXA result that does not fit your history or how strong you feel.
- Have osteopenia or osteoporosis and want more than a category.
- Want someone to sit down and explain your numbers until they make sense.
- Would rather skip the X-rays when you have the choice.
Where DEXA is still the right call
- Your doctor or insurer needs a DEXA for a diagnosis or a prescription.
- You want to extend a long DEXA record on the same machine.
See your doctor first if you have a recent fracture from a minor fall, new height loss, or sudden back pain. REMS does not detect vertebral fractures.

Straight answers
The questions we hear most.
Is REMS better than DEXA?
It tells you more. Both give you a T-score, and on average they agree closely. REMS adds a Fragility Score, uses no radiation, and is designed to ignore the arthritis and calcification that can distort a spine DEXA. DEXA is still what insurers and prescribers require, so the two work best together.
What if my REMS and DEXA results disagree?
They sometimes do, because they measure bone differently. A difference is useful information. It can point to something affecting one of the readings, such as arthritis in the spine. We go through both with you and explain what is likely behind the gap.
Will I still need a DEXA?
Probably, when your doctor or insurer asks for one. Keep the two as separate records. They should not be merged into one trend line.
Will my doctor use the results?
Many will welcome the extra information, and some will stay with DEXA alone. Either way, you will understand your own report and walk into your next appointment with better questions.
Is REMS covered by insurance?
Do not count on it. Our fee is $300.
