Echo Light Ultrasound Bone Density

Now accepting appointments!

Ultrasound technology for assessing bone density and bone quality of the lumbar vertebrae and proximal femur through a revolutionary approach to characterise bone microarchitecture using radio frequency signals acquired during a simple ultrasound scan. The method overcomes common limitations of DXA (Dual-Energy X-ray Absorptiometry) and is radiation-free.

Radiofrequency Echographic Multi Spectrometry

Radiation-free technology for assessing bone density and quality on the lumbar vertebrae and proximal femur through a revolutionary approach to characterise bone microarchitecture using radio frequency signals acquired during a simple ultrasound scan. The method overcomes all the main limitations of DXA (Dual-Energy X-ray Absorptiometry) and QUS (Quantitative Bone Ultrasound).

What is the difference between a DEXA scan and a REMS Echolight scan?

  • DEXA utilizes ionizing radiation or X-ray while REMS utilizes ultrasound waves.
  • DEXA is very dependent on factors like patient positioning, scoliosis, metallic hardware and bone spurs, unlike REMS which can be performed even in these clinical situations.
  • A major advantage of the REMS technology is the evaluation of both Bone mineral density (BMD) and Fragility (bone quality) both in one exam (bone density and bone quality). The DEXA scan does not evaluate both unless there is a TBS software package and even then, the DEXA TBS evaluates only lumbar spine only, and not the femoral neck.
  • European research studies have demonstrated a high correlation of REMS BMD to DEXA BMD and that REMS offers significantly increased levels of accuracy, sensitivity to bone mass changes, and diagnostic reproducibility over DEXA.
  • Measure of bone quality is better than BMD alone in predicting fracture risk.
  • The REMS Fragility Score, coupled with the absence of ionizing radiation, allows for osteoporosis diagnosis at an earlier stage and more accurate monitoring post diagnosis.
  • Although those who are closely following their bone health would do better to compare their DEXA exam results with follow up DEXA exams and REMS exam results to follow up REMS exams, unlike DEXA, REMS may be possible to detect changes in bone density and quality in as early as 4-6 months, unlike DEXA which may typically take 1-2 years. Hence REMS could allow closer follow up and monitoring. This is a huge benefit for those who may need to evaluate treatment response for osteopenia or osteoporosis.

Is this exam covered by insurance?

The REMS Echolight exam is not currently covered by Medicare and commercial insurances. However, there is a Category III CPT code that is available for this exam, and we can submit to your insurance a claim with this code to inform clinical efficacy, utilization, and outcomes of this technology to help allow future insurance coverage.

FDA Approved

The most advanced bone densitometer for bone health assessment for your daily clinical activities.

Through an ultrasound scan of axial anatomical sites such as the spine and femur, this innovative technology allows to measure bone mineral density without using
ionising radiation, by processing a true bone identity card. Besides ensuring a high level of accuracy, it does not require radiological protection, it is easy to use and its distinctive transportability facilitates the use thereof among patients hospitalised with fractures who cannot be transferred and the continuity of care at home.

Furthermore, the absence of radiation allows this method to be used on a
heterogeneous variety of patients, including paediatric patients, patients at risk of secondary osteoporosis, diabetic patients, patients who have undergone cancer treatments and pregnant women.

Why R.E.M.S Echolight


The first ultrasound system that allows access to prevention, early diagnosis of osteoporosis and monitoring through primary healthcare. EchoS is able to evaluate the state of bone health of people no longer with the use of X-rays, but with a simple ultrasound done directly in the doctor's office or even in your own home.

Age 21+

The lack of radiation and database including those who are 21 years and older, allows early in life screening for osteopenia/osteoporosis to help proactively take early precautionary measures to minimize future risk of fracture and overally live with optimal bone health.

Quick Scan

The ultrasound scan lasts just 80 seconds for the spine and 40 for the femur, allowing for accurate prevention, diagnosis and monitoring of bone health without the limitations of patient positioning and manual image segmentation.

Immediate Report

The exam produces an immediate medical report which, in addition to including all the most common parameters used in the diagnosis of osteoporosis, BMD (g/cm2), T-Score, Z-Score also includes the independent evaluation of the internal bone structure which provides an frailty index and body composition index.

Portable Solution

We are able to provide mobile service for residential homes and facilities, upon request.

Allow Short Interval Follow Up

Useful to monitor treatment, as it may be possibly detect changes in as early as 6 months (unlike DEXA which may take 1-2 years)​​​​​​​.

What Does Echolight Measure?

1. Bone Mineral Density (BMD)
This is the actual measurement of bone density, typically measured in grams per square centimeter (g/cm2). BMD is used to determine the T-score and the Z-score.

2. T-Score
This is a numerical value that compares an individual's BMD to the mean BMD value of a large database of healthy 30-year-old women. A T-score with a standard deviation of -2.5 from the mean value indicates

3. Z-Score
Similar to the T-score, the Z-score compares an individual's BMD to the BMD of people of the same age and gender.

4. Fragility Score
This is a measure of bone quality, indicating how likely someone is to sustain a fragility fracture. It is derived through statistical calculations using data obtained during the Echolight scan and comparing it to a database
of people with and without fractures.

These data points collectively provide valuable information about bone health,
including the risk of osteoporosis and fragility fractures.
