What is REMS?
REMS (Radiofrequency Echographic Multi-Spectrometry) is a radiation-free ultrasound technology to assess bone health. It provides insight into both bone density and bone quality, quickly and comfortably.
How does REMS work?
A specialised ultrasound probe is placed at the hip or lumbar spine. REMS doesn’t just create a grey-scale picture — it captures the underlying radiofrequency (RF) echo signals from bone. Thousands of signals are analysed and compared to large reference datasets to estimate bone mineral density and aspects of micro-architecture.
- Comfortable scan at hip and/or lumbar spine
- Advanced analysis of raw ultrasound RF signals
- Immediate results, explained on the day
Background of REMS technology
Developed in Italy by Echolight, REMS has grown over the past decade with international validation and adoption across Europe and beyond. It is known for excellent reproducibility and its unique focus on bone quality in addition to density.
In UK primary care, REMS is increasingly used to support early identification of risk and to personalise preventive care pathways.
REMS vs DXA
REMS (Ultrasound-based)
- Radiation-free ultrasound with analysis of RF echo signals
- Provides bone density and a Fragility Score (bone quality)
- Often less affected by degenerative changes at the spine
- Comfortable, quick scan with immediate results
DXA (X-ray–based)
- Widely used X-ray technique for bone mineral density (BMD)
- Strong reference data and guideline familiarity
- May be influenced by osteophytes/degenerative change at the spine
- Reports BMD (quality insights vary by context)
What do the results show?
Bone Mineral Density (BMD)
An estimate of bone density at the lumbar spine and/or hip. This helps understand where your bone strength sits compared with typical values for your age and sex.
- Discussed alongside your history and risk factors
- Useful baseline for monitoring change over time
Fragility Score (bone quality)
REMS provides a Fragility Score, which reflects aspects of bone quality and toughness — going beyond density alone. It helps distinguish people with similar density but different true fracture risks.
What happens after the scan?
You’ll receive an immediate explanation of your BMD and Fragility Score in the context of your lifestyle and medical background. From there, you’ll leave with a practical, personalised plan.
How can I improve or protect my bones?
Lifestyle & nutrition
- Diet: Prioritise adequate calcium and protein intake.
- Vitamin D: Sensible sunlight exposure and supplements when required.
- Exercise: Weight-bearing and resistance training to stimulate bone and strengthen muscles.
- Smoking & alcohol: Cutting down or stopping supports bone health and balance.
Medical options (if indicated)
- HRT: Can help protect bone in post-menopausal women.
- Bone-building medicines: Bisphosphonates, denosumab, or anabolic agents may be considered where fracture risk is higher.
- Other therapies: Tailored to your history, risk, and preferences.
Your plan is based on your personal results and goals. We’ll guide you on the most appropriate steps and timing.
