Bone densitometry, also called dual-energy x-ray absorptiometry (DXA), is a low-dose, non-invasive x-ray that is used to measure bone mineral density (BMD) and is most often used to diagnose osteoporosis and detect possible bone loss.
A BMD test can track the effectiveness of treatment for osteoporosis and assesses an individual’s risk for developing fractures. The risk of fracture is affected by age, body weight, history of prior fracture, family history of osteoporotic fractures and lifestyle issues such as cigarette smoking and excessive alcohol consumption. The results of the scan are graphed and compared to a population at peak bone mass (young normal), as well a population that is matched to your age and gender.
