Measurement of bone mineral density (BMD) with dual-energy X-ray absorptiometry (DXA) is widely used in clinical practice for the diagnosis of osteoporosis and assessment of fracture risk. However, variants and artefacts such as, osteophytes and metallic objects can affect the BMD results of the spine and hip. We demonstrate a spectrum of clinical examples that may impact on BMD evaluation. Recognition of such artefacts is important for the correct interpretation of these studies.
