Abstract

Abstract Dual-energy X-ray Absorptiometry (DXA) is the most widely used technique in clinical practice to assess changes in bone mineral density (BMD) and to predict fracture risk. Its application to lumbar spine and proximal femur BMD measurements is extremely useful in diagnosing bone mass decrease and implementing therapeutic interventions. As a consequence, its use in clinical practice requires capacity to tailor procedures to individual cases, knowledge to prevent potential sources of error, to provide measurement reproducibility and analysis, and interpretation abilities. Its advantages include the use of low radiation doses, short scan time, high precision and good patient acceptance.
