The gold standard for bone mineral density adopted by the International Health Organization is the result of dual-energy X-ray testing, which is currently a relatively accurate bone density detection method. The mainstream bone densitometers on the market are divided into two categories: dual-energy X-ray absorptiometry bone densitometer and ultrasound bone densitometer. So there are what differences between these two series, which one has more advantages?
The dual-energy X-ray absorptiometry bone densitometetry is the X-ray tube passing through a certain device to obtain two kinds of energy, namely low-energy and high-energy X-rays. After the X-ray penetrates the body, the scanning system sends the received signal to the computer for data processing to obtain the bone mineral density.
Advantages: The detection accuracy is high, and the World Health Organization (WHO) recommends it as the clinical gold standard for evaluating bone mineral density.
Disadvantages: There is a small amount of radiation, which is generally not used to measure infants and pregnant women;
High cost of use.
Due to price factors, it is usually used in large and medium-sized comprehensive medical institutions.
