Bone density scanning also called dual energy x-ray absorptiometry (DEXA) or bone densitometry is an enhanced form of an x-ray technique that is used to measure bone loss, and provide a more detailed imaging assessment to measure bone mineral content and density and help identify fragile bones before a break occurs. An x-ray is performed over the lower spine and hips.

Bone densitometry is most commonly used to diagnose osteoporosis, a condition most common in woman after menopause but may also be found in men.  Osteoporosis involves a gradual loss of calcium as well as structural changes causing the bones to be more fragile and more likely to break.  

Bone densitometry is also used in tracking the effects of treatment for osteoporosis and other conditions that cause bone loss.  
The DEXA test can also assess an individual’s risk for developing fractures.  The fracture risk is affected by age and body weight, among other variables such as cigarette smoking, excessive alcohol consumption and previous osteoporotic fractures.  Bone density testing is strongly recommended in a post-menopausal woman not taking oestrogen.
