We strontium users know that BMD results by DXA scan will be artificially high, especially after years of using strontium salts. Here is good news! Echolight REMS technology is NOT AFFECTED by STRONTIUM. It uses ultrasound instead of ionizing radiation. Echolight is a modern ultrasound device capable of measuring bone at the hip and the spine using Radiofrequency Echographic Multi Spectrometry (REMS).
BMD measured by ultrasound is not affected by the strontium content of bone. An in vitro study concluded that aBMD measured by DXA was prone to overestimation in the presence of strontium, but acoustic parameters measured by quantitative ultrasound (QUS) are independent of strontium concentration.

Another advantage of Echolight scans is that they assess the bone internal micro-architecture. So, physicians obtain results of bone quantity and quality.
Yet another advantage of REMS over DXA is that REMS appears to be able to overcome common artifacts such as structural alterations caused by OA (osteoarthritis) at the lumbar spine, which affect the BMD values obtained by DXA

Echolight has received 510(k) clearance to sell its EchoS Systems in the USA! Companies must submit a Premarket Notification, also called a PMN or 510(k), to the FDA so that it can review the product and clear it. Once the FDA declares that a new medical device is substantially equivalent to a predicate, it is cleared and can be marketed and sold in the USA.
Echolight has opened a headquarters in NYC. The scans are not available everywhere. You will have to shop around. One early adopter is Dr. Andrew Bush, M.D., an orthopedic surgeon with a practice that performs Echolight scans in Sanford, North Carolina.
COPA Healthcare LLC, Dania, FL sells the EchoS/Echolight and Marodyne LiV. The website includes a video that shows the EchoS equipment and how the scan is done. The website makes it easy to leave a message in case you have questions.
