Echolight scan
Also called: Echolight REMS device, ultrasound bone densitometer
What it means
An Echolight scan (also called REMS) uses sound waves instead of X-rays to estimate bone density, usually at the spine and hip. It's a newer alternative to the standard DEXA scan.
It can offer a radiation-free way to track bone density, which matters if you want another option for monitoring your bone health over time.
An Echolight scan is a type of ultrasound bone densitometer that uses REMS (radiofrequency echographic multi spectrometry) technology. Instead of X-rays like a DEXA scan, it sends sound waves through bone and analyzes how they bounce back. The device estimates bone mineral density and gives a T-score, similar to what a DEXA scan reports.
This technology is newer than DEXA, which has been the standard for decades. Some clinics and researchers are interested in it because it avoids radiation exposure and the equipment can be more portable. It may be used at the lumbar spine or femoral neck, the same common sites checked with DEXA.
If your doctor or a clinic offers an Echolight scan, it's reasonable to ask how it compares to DEXA for your specific situation, since DEXA remains the most widely validated and studied method for diagnosing osteoporosis and tracking bone density changes. Your prescriber can help you decide which test fits your needs best.
Echolight scans use sound waves, not X-rays, offering a radiation-free way to track bone density.
