Understanding your results: BONE DENSITY
For an explanation of BONE QUALITY results, click HERE.
Bone density and quality results from EchoS are available immediately.
Two scans are done; one on your lower spine and the second on your left hip. If the left hip can't be scanned (you might have had a hip replacement for instance) the right hip will be done.
The results will show a number of scores/figures
Bone density is measured in g/cm
The report you will receive will show your BONE DENSITY and also another graph to show your BONE QUALITY.
THIS IS YOU - ON THE DAY OF YOUR SCAN
This is your bone density reading at the time of the scans (the spine result is shown here).
The top and bottom black curved lines illustrate where the results for 95% the population lie.
The middle black curved line is the "mode" (the most common bone density) according to age.
This is the bone density of your spine when compared to a healthy 30-year-old of the same gender as you.
A Z-score compares the bone density of your spine to the average bone density of people your own age and gender.
The FRAX score shows your risk of a major osteoporotic fracture (including the spine, hips and arm bones) in the next 10 years. The individual risk of sustaining an osteoporotic fracture of your hip in the next 10 years is also shown.
These are the bone density readings for each of your upper four lumbar vertebrae
SO WHAT DO ALL THESE NUMBERS MEAN?
Your bone densities are compared to those of a population of healthy 30-yr olds (this is the T-score).
A score of 0 means your bone density is equal to the norm for a healthy young adult. Differences between your bone density and this healthy young adult norm are measured in units called "standard deviations".
The more standard deviations below 0, (indicated as negative numbers) the lower your bone density and the higher your risk of fracture.
A T-score greater than −1.0 is considered normal or healthy.
A T-score of between −1.0 and −2.5 indicates reduced bone density when compared to the average 30yr old. This is not osteoporosis but "OSTEOPENIA", a transitional state between normal and osteoporosis.
A T-score of −2.5 or lower indicates that you have osteoporosis. The greater the negative number, the more severe the osteoporosis.
