Dual-energy X-ray absorptiometry (DXA) is a widely used technology used to diagnosis osteoporosis and monitor changes in bone mineral density (BMD).The present paper reviews the clinical application of DXA in evaluating osteoporosis, including indications for BMD testing, interpretation of DXA results, diagnosis of osteoporosis, and serial BMD follow up.As the clinical utility of DXA depends on the quality of the scan acquisition, the precision assessment of DXA is also discussed.(Korean J Med 2019;94:268-272)
