The Echolight REMS test is a radiation free test for bone density now offered in the United States. It has been offered in Europe since 2010. In this article I’ll share the differences between the Echolight REMS test and the DEXA scan for bone density. I’ll also share my experience with getting the REMS test.

What is the Echolight REMS
Echolight REMS is a non-invasive bone health test designed to evaluate bone density and quality. REMS stands for radiofrequency echographic multi-spectrometry. Unlike DEXA scans, which measure bone mineral density (BMD) using X-ray technology, Echolight REMS employs ultrasound waves to assess bone characteristics, including density, microarchitecture, and strength.
Key Differences Between REMS and DEXA
- DEXA Scans measure bone mass density by using X-ray beams. The resulting images provide information about bone density and risk of fracture.
- Echolight REMS utilizes ultrasound waves to evaluate bone properties, including density, microarchitecture, and biomechanical properties.
- DEXA scans are considered the gold standard in the US for measuring BMD and assessing fracture risk but do not assess bone quality or structure.
- Echolight REMS offers a more comprehensive evaluation of bone health by assessing multiple parameters, including density, structure, and strength. It provides insights into bone quality, which may be valuable for predicting fracture risk, particularly in conditions like osteoporosis.
- According to a 2021 study the precision error of REMS (root-mean-square coefficient of variation) was 0.32% for the femoral neck and 0.38% for the lumbar spine, which is a much smaller error compared with that of DEXA (estimated to be 1.47% for the femoral neck and 1.26% for the spine).
- DEXA scans involve exposure to low levels of ionizing radiation, although the dose is minimal compared to other imaging techniques. However, repeated exposure over time may pose concerns, especially for certain patient populations. REMS can be used during pregnancy to assess bone health.
- REMS scans can be done in a doctor’s office setting.
- REMS testing locations are very limited in the United States and are not yet covered by insurance.
Where Can You Get Echolight REMS Test
I personally contacted Echolight by sending them an email and asking for their locations in the United States. Their email is on their website and they responded very quickly. You can also request a virtual demo here.
Below is a list of locations in the United States and Canada that they provided, however, I strongly recommend that you contact Echolight yourself because as more people learn about the test, there will be more locations. I also recommend that you educate your healthcare providers about the test.

My Experience
I went to the Thermography Center of Dallas and paid $150 for the Echolight REMS scan. The ultrasound was easy and with the consultation, I was there for about 45 minutes. I had recently had a DEXA scan in January 2024 that showed that all areas had improved from osteoporosis to osteopenia except my right hip. The REMS scan shows osteopenia in all areas but with lower (improved) levels. The image below shows my latest DEXA scan and the results from the REMS scan.
Of course, I am happy that all sites tested show osteopenia (not osteoporosis) but I do take into account that the tests were 3 months apart and that clinical studies show that the REMS test is as or more accurate than the DEXA scans. I will continue to optimize my bone health with the end goal of having normal bone density and low fracture risk. And, I will continue to monitor the clinical research and will get the REMS scan once a year. Hopefully, eventually it will be offered in every state and be covered by insurance!
