Understanding Bone density Results
As you can see from the page, for each part of the body (left arm, left leg, left ribs, T-spine etc) you get an overall size of the bone, and an overall weight. This weight in grams is the dry weight of the bone – in other words, the weight of the dry calcium in your bones. Then there is a calculation of bone density with divides one by the other. You get a bone density for each part of the body, and then a total.
The T-Score doesn’t compare you to your own age group, but rather compares your bone density to what is considered ‘peak’ bone density – which is usually a healthy 30 year old, or thereabouts. Once again it is expressed in standard deviations, so a positive value means you have more dense bones than average, and a negative value means your bones are less dense than average.
