What is the role of dual-energy X-ray bone density testing?

Nowadays, people's scientific and technological power is very strong, especially in the field of medicine, people will invest a lot. After all, the body is the capital of revolution, and only by ensuring the health of the body can more things be accomplished. Examination is a very important part in the medical field. It can effectively find out whether the human body has a disease or understand the progress of treatment when treating a disease. Dual-energy X-ray bone density is a very common method, so what is its role?

Dual-energy X-ray absorptiometry is a test for bone density, which is an important test for diagnosing osteoporosis. When the bone density is lower than 1.0, the bone mass is normal. If it is between 1.0 and 2.5, it is osteopenia. If it is greater than 2.5, it is osteoporosis. After suffering from osteoporosis, active calcium supplementation and vitamin D treatment should be carried out, and anti-osteoporosis drugs such as alendronate or estrogen drugs should be used at the same time, and active functional exercises should be carried out to prevent pathological fractures.

Dual-energy X-ray bone density test

This test is also called dual-energy x-ray absorptiometry. The two energies obtained through the x-ray tube through a certain device are low-energy and high-energy photon wind. After this photon wind penetrates the body, the signal received by the scanning system is sent to a computer for data processing, thereby obtaining the mineral content of the bone.

This instrument can measure the bone mass in any part of the body with high accuracy and relatively little harm to the human body. The radiation dose measured in one part is equivalent to one thirtieth of that of a chest X-ray, so there is no problem of any radiation source transmission.

This examination is currently being carried out in all major hospitals across the country. It is widely used and its measurement results are relatively accurate, and it has strong clinical reference value.

Dual-energy X-ray absorptiometry can measure and evaluate bone minerals. This bone density examination method is widely used in the diagnosis and prevention of clinical osteoporosis in orthopedics, endocrinology, rehabilitation physiotherapy, obstetrics and gynecology, etc. It is especially important for the differential diagnosis of various low back and leg pain diseases in the elderly and is the gold standard for diagnosing osteoporosis. Its advantages: advanced performance, systemic, short time, high precision and accuracy, and low radiation dose; it can measure bone density and fat tissue content in the lumbar spine, proximal femur, and whole body bones.
