Radiofrequency Echographic Multi Spectrometry (REMS) for the evaluation of bone quantity and quality
What is Echolight?
Radiofrequency Echographic Multi Spectrometry (REMS) for the evaluation of bone quantity and quality.
Current Available Methods for Bone Health Assessment
DEXA
Ionizing Radiation Method
- Evaluates axial sites: Lumbar Spine (L1-L4) and Femoral Neck
- Provides BMD/T-score/Z-score
- 10-year FRAX
Echolight REMS Technology
Ultrasound Method
- Evaluates the same axial sites as DEXA
- Provides BMD/T-score/Z-score
- Fragility Score
- 5-year fracture risk
Peripheral QUS
Ultrasound Method (radius, tibia, calcaneus, phalanges)
- Does not assess axial sites
- Provides bone density index (not BMD)
- Not to be confused with REMS
REMS Ultrasound Scan
REMS Technology
REMS allows bone health evaluation by means of a rapid ultrasound scan on reference axial sites:
80s
Lumbar vertebrae scan
40s
Proximal femur scan
Echolight Process Flow
US Acquisition
Software-guided ultrasonographic scan
B-Mode Image
Automatic identification of bone interface and Region of Interest
RF Signal ROI
Analysis of raw frequency data
Data Analysis
Quantitative Parameters
Qualitative Parameters
Key Benefit: Automatic Artifact Exclusion
REMS processes the raw data of 256 scan lines, automatically eliminating signals that belong to calcifications, osteophytes, hardware, and other artifacts.
Fragility Score and Fracture Risk Prediction
Fragility Score is a REMS-based parameter providing a direct estimation of skeletal fragility.
Quantitative Data (T-Score) and Qualitative Data (Fragility Score) are combined to determine Fracture Risk.
Fracture Risk Prediction
| Risk class | Risk of major osteoporotic fracture per 100 subjects at 5 years |
|---|---|
| R1 | ≤ 0.5 |
| R2 | [0.5-1.0] |
| R3 | [1.0-2.0] |
| R4 | [2.0-3.5] |
| R5 | [3.5-6.0] |
| R6 | [6.0-10.0] |
| R7 | > 10.0 |
Each risk class is associated with the probability to have an incident fragility fracture in five years (conventional tools provide the probability in ten years).
Advanced Body Composition Analysis
Automatically generated during the 80-second scan of the lumbar spine.
Body Composition
Quantitative Fat Mass, Fat Free Mass, Body Water, and Proteins/Minerals
Fat & Visceral Fat
Body Fat Percentage and Visceral Fat Level
Metabolic Rate
Basal Metabolic Rate and Activity-based Metabolic Rates
