Bone mineral Density: Who needs regular testing?

Bone density is an important measure of bone health, which helps determine the amount of calcium in the bones and the strength of the bones.

Bone density is an important measure of bone health, which helps determine the amount of calcium in the bones and the strength of the bones. The following groups of people should pay special attention to bone density and be checked regularly:

1.Fracture population over 50 years old

If you are over 50 years of age and have had a fracture for any reason, a bone density test is recommended. Fractures can be an early sign of osteoporosis, and early detection can help take effective preventive measures.

2. Senior population: 65-year-old women, 70-year-old men

Bone density tests are also essential for women over 65 and men over 70. At this time, the degree of bone fragility may have increased, and early detection of the problem can be timely intervention and treatment.

3. Postmenopausal women and high-risk men

Postmenopausal women (especially those between 50 and 65 years of age) and men between 50 and 70 years of age who have risk factors for fracture, especially symptoms of osteoporosis (such as active back pain, reduced height, hunchback, etc.), should also have regular bone density tests.

4. Patients with diseases related to bone loss

Common bone mineral density test method

1.Ultrasonic bone mineral density detection: Ultrasonic speed and amplitude attenuation are used to reflect the bone mineral content and bone strength. Ultrasonic measurement is sensitive to soft tissue, bone tissue, bone marrow tissue and other structures, usually the tibia and radius are measured. It is mainly used for the screening of people at risk of osteoporosis and the risk assessment of osteoporotic fractures.

2. Dual-energy X-ray bone Mineral density Test (DXA) : By penetrating the bone and soft tissue with two different energy X-rays, bone mineral content is calculated to obtain the bone mineral density value. It has the advantages of high accuracy, short measurement time, simple operation and high safety, and is widely used in major hospitals and physical examination institutions.
