What is the density of bone minerals?
Bone mineral density (BMD) is the measurement of the most important minerals that are present in human bone structure. The most popular, these minerals include calcium, which is largely responsible for maintaining the strength and integrity of bones. The density of bone minerals is measured by scanning computer tomography (CT) or X -ray, and this measurement becomes increasingly important as one ages.
The mineral content in the bones naturally decreases as a person ages, and the loss of too much calcium can lead to osteoporosis and in fragile bones that are easy to break. Precise measurement of bone mineral density can pretend later problems. Preventive measures such as receiving calcium supplements, proper exercise or even initial hormonal therapy can begin with sufficient warning.
The density of mineral bone minerals is something that should most concern women who are over 65 years old. Men can also get osteoporosis but more often in ŽENES. Screening for women is recommended.
people who are afraid of mineral densities in bones can talk to their doctor or other doctor to ask for ultrasound. This non -invasive test, usually performed on the heel of a person, will not accurately measure the exact percentage of mineral density, but can be used to find problems. From there you can perform other tests to get more accurate results. BMD tests are usually performed every two years and are often performed as monitoring of osteoporosis treatment because the number reveals how well the treatment works.
There are many ways to measure BMD exactly. Quantitative Computer tomography is a CT scan used to measure the bone density of the spine. The dual energy of X -ray absorption uses a pair of X -rays to measure bone density in the sides and spine of man. Thje non -invasive method can detect bone loss already small 2 percentage points.
peripheral dual energy X -ray absorption is similar to X -ray absorption with dual energy. The peripheral version of this test can measure the density of different bones, such as the hands and feet. Dual absorption with dual photon also measures bone density in the spine and hip, this time using a small amount of radioactive substance.
spine and hips are usually tested because they are among the most likely bones that break in older individuals. Results are usually in the form of T-Skóre, which compares the results of tests with BMD of a normal, healthy, 30-year-old. BMD of most people of this age falls into a narrow range, making it an excellent control group. The negative number means that the tested bones are thinner than a typical 30 -year -old and a positive score means they are stronger. If the results are given in the form of Z-score, this means the results of an individual's test compared to the results of other people similar races, age and gender.
