What is a bone density test and how is it done?

Bone density test is BMD

Tests are a test to determine bone health, identify osteoporosis, prevent fracture risk, and monitor the effectiveness of osteoporosis. Bone density can be measured on many parts of the human body, such as hips, spine, wrists, heels, etc.

Summary. Hello, dear, the bone density test report is mainly divided into two parts: charts and values, as long as you use some curves to show your bone density and normal people or peers related to the trend of high and low changes, the values mainly include T value and Z value. The t-value is mainly to compare your bone mass with that of a normal healthy young person to compare this standard deviation, if the t-value is between -1 and 1, then it means that the bone density value is normal, if it is between -1, it means that there is osteoporosis and bone loss.

If it is less than that, then it means that there is severe osteoporosis. The other is the z-value, the z-value is based on the comparison of normal people of the same age, if the z-value is less than or equal to -2, then it means that your bone density is lower than that of normal peers.

Hello, dear, the bone density test report is mainly divided into two parts: the graph and the value, as long as you use some curves to show your bone density and normal people or peers related to the high and low change trend, the value mainly has T value and z value. The t-value is mainly to compare your bone mass with that of a normal healthy young person to compare this standard deviation, if the t-value is between -1 and 1, then it means that the bone density value is normal, if it is between -1, it means that there is osteoporosis and bone loss. If it is less than Danzhong, then it means that there is severe osteoporosis.

The other is the z-value, the z-value is based on the comparison of normal people of the same age, if the z-value is less than -2, then it means that your bone density is lower than that of a normal peer.

My result is a t-value z-value.

In the test of bone mineral density, the main thing to look at is the t-value, which is normal under normal circumstances: -1 t-value 1 indicates that the bone mineral density value is normal; A value of -1 indicates low bone mass and bone loss; A t-score of yes indicates osteoporosis. A z-score of -2 indicates that the bone mineral density is within the normal peer range; A z-score of -2 indicates that bone mineral density is lower than normal.

If you are found to have osteoporosis, you need to take calcium tablets to supplement calcium, improve your diet, and do not engage in strenuous exercise to avoid fractures.

Isn't the t-value between -1 and 1?

You didn't say anything greater than 1.

That's normal, dear.

In general, the standard deviation is within the standard deviation, and if the patient's t-score is less than that, it indicates osteoporosis. In addition, it is necessary to look at the z-value, which means that the bone density of the person suffering from astatism is compared with the normal elderly people of that age or their peers. If the standard deviation of the z-value is less than -1, it indicates that the patient's bone mineral density has decreased, and there is porosis relative to the same age.

If the patient is not sure whether he has osteoporosis or will not read this kind of report, he can go to the orthopedic clinic with the report of the side crack and ask the doctor to interpret it on the spot.

Many people who attach great importance to physical health will attach great importance to physical examination for themselves and their children every year, for the human body, the absorption of calcium has an important impact on the body, calcium intake may affect the bone density of the human body, then many people will also choose to check the bone density for themselves and their children, then the bone density is mainly used to check the bones of the human bodyMineralsdensity, which is the strength of the bonesWhether the standard is metAn important point. So now some means of checking bone density, mainly using ultrasound to check, is very fast and convenient, so is it really useful to do bone density checks? We analyze the following two aspects.

We all know that children are growing upGrowth and developmentIt is very fast, so the metabolism is also very fast. Therefore, if parents want to know how their children are growing, they can mainly observe them, or let their children have physical examinations in the hospital every once in a while. Look at the doctor for the childIndicators of physical examinationWhat kind of judgment there is, parents basically know what the child's physical condition is, and there is no need to take the child to do a bone density test alone, because the childGrowing too fastEven if you take your child to have a bone density test, the value may change after a few days, so there is no need for this.

Then, the bone condition of adults, especially middle-aged and elderly people, and children is completely different, and adults, especially middle-aged and elderly people, have long been stereotyped in the development of high bones. In everyday life is to give bonesSupplemental nutritionAs you age, the nutrients of your bones will be lost, and if you feel that your physical condition is not so good, you can actually go for a bone density test.

Middle-aged and elderly people actually shouldDo it every yearA bone density test to see if you are calcium deficient or deficient. The phenomenon of other elements. If there are these phenomena, they can also be supplemented in a targeted manner, which is still very good for the health of the body.

I think it's certainly useful because it allows you to check your development and determine if you are deficient in calcium and other elements.

I think it is certainly useful, so that you can find out if you are deficient in calcium and make timely calcium supplementation.

It is useful to check the density of the bones and understand the condition of the bones.

1. What is "bone density"?

Bone mineral density, or bone mineral density, is a major indicator of bone strength, expressed in grams per square centimeter (g cm2). The bone density value is an absolute value. The absolute value of different bone densitometry is not the same.

Therefore, people usually use the t-score to judge whether their bone density is normal. The t-value is a relative value, and the normal reference value ranges from -1 to.

1. When the t-value is lower, it is abnormal.

2. Children should have regular bone density tests.

Osteoporosis is a serious public health problem worldwide. Scientific research has found that the bone mineral density value in the early stage of life is the best indicator of bone condition in the later stage, and whether the bone mineral density of children and adolescents is normal is of great clinical significance.

Bone density testing in children by means of an instrument allows the determination and quantification of the mineral content in children's bones in vitro. Bone minerals include calcium, phosphorus, magnesium, etc., and the main component is calcium, so it is also called bone calcium. Whether the bone calcium content is normal or not directly affects the toughness of the bones and the strength of the physical fitness.

There are no obvious symptoms in the early stage of bone mineral loss, and children are regularly tested for bone mineral density, and bone mineral can be detected in time even if there is a trace of bone mineral loss, so as to facilitate early diagnosis and**.

3. How many methods are there for bone density testing in children?

Current methods of performing bone density tests in children include:

Single-photon bone densitometer test - mainly used to measure bone density of the radius and ulna of the forearm. This method has a large error in measuring bone density.

Dual-energy X-ray absorptiometry test – mainly measures the bone density of the lumbar spine, patella, tibia and other parts. It has the advantages of high precision, small error and high diagnosis rate.

Ultrasonic absorptiometry test——

It is used to measure bone density in the radius, calcaneus, patella, tibia, etc. The test results can not only accurately reflect the level of bone density, but also scientifically reflect the condition of bone structure. It has the advantages of no radioactive source, high precision, fast and convenient, and low cost.

Analysis: Hello, there is a special instrument to check bone density, and there is no need to draw blood.

Suggestions:

Analysis: Hello, you can accompany the ruler to find out whether the individual's physique belongs to the high-risk group of osteoporosis, opinions and suggestions: because the incidence of osteoporosis is 50% of people over 50 years old, it is prone to fractures, and the most common fractures are the three parts of the femoral neck, spine and radial ulna, so the bone density test is for this situation, with targeted examination.

You can test your height.

Determine the risk of fracture and the presence or absence of calcium loss.

1. Young and middle-aged women:

Bad lifestyle habits are constantly invading the health of urban people, and osteoporosis is gradually appearing early. In the age group of 25 to 35 years old, more than 50% of white-collar women have more serious bone loss than men, and the incidence rate is significantly higher than that of men. Women feel back pain, a considerable part of which is an early symptom of osteoporosis.

Nowadays, many young women are prone to osteoporosis due to dieting**, sitting more and moving less, and eating an unbalanced diet.

Men who smoke and drink heavily:

Due to smoking, alcoholism, and metabolic diseases such as obesity, diabetes, and high blood pressure, bone mass in middle-aged men begins to decrease. If you are experiencing fatigue, body aches and fatigue, fatigue, sweating, numbness, cramps, etc., it is necessary to have a bone density test.

2. Children who like carbonated drinks:

Children who regularly drink large amounts of carbonated beverages have three times the risk of fractures compared to other children. Children who watch too much TV or computer space are at greater risk of osteoporosis in adulthood due to lack of outdoor exercise. In addition, obese and picky eaters should have their bone density checked.

Postmenopausal women:

3. When women's menopause comes, the decline in bone mass is obvious, and the measurement of bone density is quite important. Measuring bone density to prevent osteoporosis is a must for middle-aged and elderly women after the age of 50. If there are additional risk factors for osteoporosis, such as corticosteroid use, smoking, and drinking a lot of coffee for a long time, it is important to get checked up once a year.

4. People with renal insufficiency, diabetes, chronic liver disease, hyperparathyroidism, etc.

5. The elderly are the key groups of osteoporosis, and we must pay attention to bone density examination.

6. People with low levels of sex hormones.

7. People with a family history of related bone diseases.

8. People with osteoporotic changes shown by X-ray examination.

9. Pregnant women should check their bone density in the first month of pregnancy and supplement calcium in time.

10. People who take drugs that may affect the metabolism of bone minerals.

Bone density test is the best indicator of osteoporosis, whether you need to do bone density, Dr. Zhu will tell you.
