What type of absorptiometry is commonly used for bone density assessments?

X-ray absorptiometry is the standard technique used for measuring bone mineral density (BMD) and is widely recognized for its accuracy and effectiveness in assessing bone health. This method utilizes X-rays to quantify mineral content, particularly calcium, in bone tissue. The most common form employed in clinical practice is Dual-Energy X-ray Absorptiometry (DXA or DEXA), which provides detailed information regarding bone density at various skeletal sites like the spine and hip.

The reasons for preferring X-ray absorptiometry for bone density assessments include its relatively low radiation exposure, high precision in measurements, and the established correlation between bone density and fracture risk. The technique allows healthcare providers to identify patients at risk of osteoporosis and other conditions related to decreased bone density, informing treatment decisions.

Other techniques listed are not as commonly used for routine bone density assessments. Each has its specific applications and limitations outside of direct bone density evaluations, which is why X-ray absorptiometry remains the gold standard in this field.
