[Non-invasive method for measuring bone mineral density].
Measurement of bone mineral density (BMD) using dual energy X-ray absorptiometry is the basis of the definition of osteoporosis. Accuracy, precision and sensitivity of the method are good enough for clinical use. Prospective studies have shown that there is a gradient of risk between the decrease in BMD, related to age and hormonal insufficiency, and the increase in the incidence of fracture. Thus, therapeutic decision is based on both BMD and clinical risk factors that contribute to fracture risk.
