Abstract

Osteoporosis is a chronic disease requiring prompt and accurate diagnosis. The most widely used quantitative bone imaging technique for estimating Bone Mineral Density (BMD) both for research purposes and in the clinical practice according to WHO, is DXA (dual-energy X-ray absorptiometry). DXA may be performed at the axial (lumbar spine, proximal femur) and appendicular skeleton (distal forearm) for the diagnosis of osteoporosis. In this review, we summarize basic considerations concerning the technique, as well as recommendations for scanning sites in different individuals.
