REMS Bone Health,
Near You

Your bone mineral density compared to a healthy 30-year-old — the primary metric for diagnosing osteoporosis and osteopenia.

How your density ranks among peers of the same age, sex, and body size.

Bone microarchitecture quality and 5-year fracture probability, reported alongside your T-score and Z-score.

Personalized probability calculated from both density and quality — not density alone.

REMS (Radiofrequency Echographic Multi-Spectrometry) is an FDA-cleared ultrasound technology that measures both bone density and bone quality. A small probe is placed at your lumbar spine and hip to capture ultrasound echo signals. Advanced software analyzes these signals in real time to determine your bone mineral density (BMD), Fragility Score, and 5-year fracture risk — all by ultrasound. The entire scan takes approximately 20 minutes.

A European multicenter study of over 4,300 subjects showed REMS achieved 90.4% sensitivity and 95.5% specificity at the femoral neck, and 90.9% sensitivity with 95.1% specificity at the lumbar spine. REMS BMD results correlate closely with DEXA for diagnosing osteoporosis. Importantly, REMS can overcome artifacts like osteoarthritis and vascular calcifications that commonly cause DEXA to overestimate bone density.

DEXA uses low-dose X-rays to measure bone mineral density only. REMS uses ultrasound to measure both bone density AND bone quality (microarchitecture), and reports a Fragility Score alongside them. REMS uses portable equipment, can be repeated as often as needed, and does not require a hospital radiology suite.

REMS uses the same class of ultrasound used in prenatal imaging. It is safe for all adults, including those who are pregnant, and can be repeated as often as your care calls for.

Medical guidelines recommend bone density screening for women age 65+, men age 70+, and younger adults with risk factors such as family history of osteoporosis, long-term steroid use, early menopause, smoking, low body weight, or prior fractures. Because REMS uses ultrasound, it is also appropriate for younger individuals seeking baseline bone health data and anyone who wants more frequent monitoring.

A REMS scan is painless and non-invasive. You lie comfortably on an exam table while a technician places a small ultrasound probe on your lower back and hip — similar to a prenatal ultrasound. The probe rests on the skin with a little gel. Preparation is minimal: wear comfortable clothing without metal buttons or zippers near your spine and hips, and empty your bladder beforehand. Avoid calcium supplements 24 hours before the scan.

REMS bone scans at HALLĒ locations typically range from $149 to $299 depending on the assessment package. This is comparable to or lower than out-of-pocket DEXA scan costs ($150–$250). All HALLĒ scans are HSA/FSA eligible. The price includes the scan, a detailed report with T-score, Z-score, Fragility Score, fracture risk assessment, and a same-day consultation to review your results.

Currently, most U.S. insurance plans and Medicare do not specifically cover REMS scans, as a dedicated CPT billing code is in development (expected 2026–2027). HALLĒ accepts HSA and FSA payments and provides detailed documentation you can submit for potential reimbursement. As REMS adoption grows and the billing code is established, insurance coverage is expected to follow.

Because REMS uses ultrasound, there is no limit on scan frequency. You can safely scan multiple times per year to closely track bone health changes. DEXA is typically limited to once every 1–2 years by clinical guidance and insurance restrictions. HALLĒ recommends reassessment every 6–12 months for individuals actively managing bone health.

The Fragility Score is a REMS-exclusive metric that evaluates your bone’s internal microarchitecture — the structural quality that determines how resistant your bones are to fracture. Two people can have identical T-scores (density) but vastly different Fragility Scores (quality). This is why some people with “normal” density still fracture, and others with low density never do. The Fragility Score estimates your personalized 5-year fracture probability.

If you have a total hip replacement, that specific hip cannot be scanned (the same limitation applies to DEXA). However, the opposite hip and lumbar spine can still be assessed. If you have spinal hardware, kyphoplasty, or vertebroplasty, inform your technician so the scan protocol can be adjusted. REMS reads through many of these artifacts, because ultrasound is not affected by the vascular calcifications or degenerative changes that commonly distort X-ray results.

Yes. In October 2024, NASA announced it is using Echolight REMS devices to monitor bone health in human spaceflight simulation studies. Astronauts lose bone mass in microgravity, and REMS’s portability and ability to scan frequently make it ideal for monitoring bone changes in space. This partnership validates REMS as a cutting-edge technology trusted for the most demanding applications.

For many people, yes. REMS provides equivalent bone density measurements plus bone quality data. However, if your physician is actively managing osteoporosis treatment using DEXA-based T-scores as benchmarks, you should discuss incorporating REMS with them. REMS and DEXA measure bone using different technologies (ultrasound vs. X-ray), so direct score comparison between the two is not recommended — each should be compared to its own baseline.

HALLĒ operates REMS scanning locations across multiple states including Florida (Naples, Jacksonville, Sarasota, Orlando, The Villages), California (Half Moon Bay), and Ohio (Dublin). Additional locations are in development. Visit our Locations page or explore by state to find the nearest HALLĒ REMS scanning center.
