What is normal BMD of spine?
What is normal BMD of spine?
The average BMD of the normal men’s group between 20 and 39 years of age was 0.996+/-0.111 g/cm(2) in the lumbar spine and 1.025+/-0.110 g/cm(2) in femoral region. The percentages of annual and total BMD losses were 0.33 and 13% at spinal level and 0.50 and 20% in femoral region, respectively.
When do you do BMD?
If you are taking medication for osteoporosis, expect to have a bone density test every 1 to 2 years. Even if you don’t have osteoporosis, your doctor may suggest that you get a bone density test every 2 years, especially for women during or after menopause.
What is a significant increase in BMD?
The measured increase in BMD of 0.040 g/cm2 exceeds the LSC of 0.031 g/cm2 and is considered a statistically significant increase in BMD.
What is BMD score?
The T-score A T-score is a standard deviation — a mathematical term that calculates how much a result varies from the average or mean. The score that you receive from your bone density (BMD or DXA) test is measured as a standard deviation from the mean.
What age is for BMD test?
Bone density tests are recommended for all women age 65 and older, and for younger women at higher-than-normal risk for a fracture. Men may want to discuss osteoporosis screening with their doctor if they’re over age 70 or at high risk for thinning bones.
Should your bone mass be high or low?
A T-score between −1 and −2.5 indicates that you have low bone mass, although not low enough to be diagnosed with osteoporosis. A T-score of −2.5 or lower indicates that you have osteoporosis….The T-score.
| Level | Definition |
|---|---|
| Low bone mass | Bone density is between 1 and 2.5 SD below the young adult mean (−1 to −2.5 SD). |
Are dense bones good?
Your bone density is considered normal. Your score is a sign of osteopenia, a condition in which bone density is below normal and may lead to osteoporosis. Your bone density indicates you likely have osteoporosis.
How do I read my BMD report?
The lower your score, the weaker your bones are:
- T-score of -1.0 or above = normal bone density.
- T-score between -1.0 and -2.5 = low bone density, or osteopenia.
- T-score of -2.5 or lower = osteoporosis.
What do my BMD test results mean?
The following information should help you understand what your BMD test results mean but you should always discuss your results with your healthcare provider. Your first BMD test tells you the density of your bones at that specific time. However, it can not tell you if you have lost bone or are losing bone.
What is the z score on a BMD test?
The T-score, as discussed above, is used to diagnose normal bone mass, low bone mass, or osteoporosis. Sometimes healthcare providers get important information about your bone health by evaluating another result of the BMD test called the Z-score.
Can I have a follow-up BMD Test at a different location?
It is ideal to have follow-up BMD tests performed on the same machine, at the same location, as your first bone density test. However, if you are not able to return to the same location, select a center that has the same model of DXA machine.
What happens to BMD after 7 years of Risedronate treatment?
In the risendronate group it was observed that one-year discontinuation after 7 years’ risedronate treatment, BMD values of lumbar spine changed + 1.3%, total hip BMD decreased − 3.2%, and femoral neck increased + 2.0%.
