Dual-energy X-ray bone density meter: Why is it the "gold standard" for bone density detection?

It can not only accurately diagnose osteoporosis, but also be used for fracture risk prediction and drug efficacy monitoring.

At present, the aging intensifies, osteoporosis has become a major threat to the health of middle-aged and elderly people. Such diseases not only seriously affect the quality of life of patients, but also can lead to serious consequences such as fractures, and bring a heavy burden to families and society. Because of this, bone mineral density testing is increasingly important for the prevention and treatment of osteoporosis. Among the many bone density detection methods, dual-energy X-ray bone densitometry (DXA or DEXA) is recognized by the World Health Organization (WHO) as the "gold standard" for the diagnosis of osteoporosis. So what's behind this?

Accurate measurement to eliminate interference

Dual-energy X-ray bone densitometers work on the basis of two X-ray beams of different energies. The device emits both high - and low-energy X-rays through the body, and because bone and soft tissue absorb X-rays of different energies differently, the detector can accurately calculate bone mineral density (BMD) by measuring the attenuation of the X-rays. This dual-energy scanning technology effectively eliminates the interference of internal soft tissue on the measurement results, and greatly improves the accuracy of the measurement.

Compared with the traditional single photon bone densitometer, the dual-energy X-ray bone densitometer has obvious advantages of accurate positioning and high measurement accuracy. Although quantitative CT can evaluate the bone mineral density of cortical bone and spongy bone respectively, the amount of X-rays received by the subjects is larger, and the equipment and detection cost are higher. Therefore, dual-energy X-ray bone densitometer, with its accurate measurement technology, has emerged in many detection methods.

Widely used to provide a comprehensive basis

In clinical application, the value of dual-energy X-ray bone densitometer has been fully reflected. It can not only accurately diagnose osteoporosis, but also be used for fracture risk prediction and drug efficacy monitoring. With this device, doctors can clearly understand the patient's bone mineral density and distinguish between different types of fracture risk, including key areas such as the hip, spine and wrist.

At the same time, dual-energy X-ray bone densitometer can also provide lumbar spine, hip, forearm and other parts, lying position, sitting position and other position options, greatly convenient patients, to achieve personalized examination. Through regular testing, doctors can monitor the rate of bone loss in patients and develop personalized, precise treatment plans.

Safe and convenient, ultra-low radiation

Dual-energy X-ray bone densitometer has the significant advantage of safety and convenience. The radiation dose of a bone mineral density test is very low, and the report can be reported at the end of the examination, without a long wait, and the results are reliable, convenient and fast. In addition, the test is inexpensive, reducing the financial burden on patients and enabling more people to benefit from this test technology.

Professional recognition, industry benchmark

Dual-energy X-ray bone densitometer has been widely recognized worldwide. The World Health Organization uses it as the "gold standard" for diagnosing osteoporosis, and organizations such as the International Osteoporosis Foundation also recommend using the device for bone density testing. In China, the results of dual-energy X-ray bone mineral density measurement are also the gold standard for the diagnosis of osteoporosis, and the detection project has been included in the routine physical examination of people over 40 years old.

With its precise measurement technology, extensive clinical applications, safe and convenient detection methods, and the recognition of professional organizations, dual-energy X-ray bone densitometer is well deserved to become the "gold standard" for bone mineral density detection. It provides a strong support for the prevention and treatment of osteoporosis and protects people's bone health. It is believed that with the continuous progress of technology, dual-energy X-ray bone densitometer will play a greater role in the future and escort the health of more people.
