Bone densitometry and osteoporosis: a practical guide
GM, 38, August, 2008
This article discusses the evolution of central dual-energy X-ray absorptiometry (DXA) as a tool for
the diagnosis and management of postmenopausal osteoporosis. The derivation of normal values is
considered and this is then linked with guidance on clinical interpretation. Peripheral densitometry can
indicate risk of fracture in certain situations, but is not covered here.
