What is normal range for BMD?
The T-score
| Level | Definition |
|---|---|
| Normal | Bone density is within 1 SD (+1 or −1) of the young adult mean. |
| Low bone mass | Bone density is between 1 and 2.5 SD below the young adult mean (−1 to −2.5 SD). |
| Osteoporosis | Bone density is 2.5 SD or more below the young adult mean (−2.5 SD or lower). |
What is a BMD medical test?
A bone mineral density (BMD) test measures how much calcium and other types of minerals are in an area of your bone. This test helps your health care provider detect osteoporosis and predict your risk for bone fractures.
What does a high BMD mean?
A high bone mineral density is one where the bone mineral density (BMD) is usually greater than two standard deviations above what is expected for age. This can sometimes be seen on routine DEXA scan assessment.
What is BMD spine test?
A bone density test is used to measure bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.
What should my bone mass be?
Bone Mass. Bone content is the percentage of bone mineral as compared to total body weight. The average bone content for adults is 3-5%. This measurement is good to keep track over a long period of time as bone mass can decline slowly with age.
What do BMD mean?
Bone Density A bone mineral density (BMD) test is the best way to measure your bone health. It compares your bone density, or mass, to that of a healthy person who is the same age and sex as you are. It can show: Whether you have osteoporosis, a disease that makes your bones weak. Your risk for breaking bones.
How is BMD done?
During the test, you lie down on a padded platform, fully clothed. A machine arm passes above you, sending low-dose X-rays through your body. Based on how much the X-rays change after passing through your bones, it comes up with an image of your skeleton. This test lasts about 10 minutes.
Is a high bone mass good?
Although everyone will lose bone with age, people who developed a higher peak bone mass when young are better protected against osteoporosis and related fractures later in life.
What is a normal lumbar spine BMD?
All lumbar vertebrae could be analysed by using the dedicated software for BMD computation. The overall mean DECT-based BMD value of L1–L4 was 86.8 mg/cm3 ± 33.5 mg/cm3 (range, 28.5–289.1 mg/cm3).
Can you have osteoporosis at 40?
You can have osteoporosis at any age and not know it — there are often no symptoms. For many women, the first sign that they have the condition is a broken bone.
