It has the advantages of short measurement time, high precision, low radiation dose and low cost. At present, it is recognized by the World Health Organization (WHO) as the gold standard for the diagnosis of osteoporosis. It can be used to scan the spine, hip joint and whole body, measure bone mineral density (BMD) and stiffness index (SI) of bones, and then make a definite diagnosis by using the quantitative diagnosis standard of the World Health Organization (WHO). The bone densitometer can also be used for fracture risk assessment, follow-up monitoring of therapeutic effect, determination of muscle/fat composition and evaluation of metabolic bone diseases, meeting the clinical and scientific research needs of orthopedics, pediatrics, obstetrics and gynecology, geriatrics, radiology, sports medicine, nuclear medicine and other disciplines. In foreign countries, it is often used by health clubs to guide weight loss and body shaping.

Clinical significance Some elderly people will think that they are old and it is normal to have osteoporosis. Just add some calcium, there is no need to do bone density measurement. In fact, most elderly people have osteoporosis, but everyone has different degrees of illness; You take calcium supplements every day. Did you make that up? What's your bone density now? Do a bone mineral density measurement, and you will be very clear:

1, the diagnosis doctor of osteoporosis judges whether a patient has osteoporosis by measuring bone density.

2, fracture risk assessment Bone mineral density (BMD) can predict the risk of fracture, through scientific methods to analyze how likely you are to have a fracture, so as to be aware of it.

3. Monitor the changes of bone mineral density. After you finish the bone density measurement, you have a bone file. By comparing the results, we can evaluate whether our treatment is effective and monitor our bone changes conveniently.

Osteoporosis is usually asymptomatic in the early stage, so it is called "silent epidemic", so it is necessary to check the bone density regularly to prevent osteoporosis.

The BMD report will automatically give your BMD measurement value, and compare it with the peak value of normal people to get the t value. According to the diagnostic criteria of osteoporosis formulated by the World Health Organization:

Normal: t value >-1

Decreased bone mass:-1
