DEXA Bone Densitometry Bone Density Scan or DEXA Bone Densitometry. Bone density scanning, also called dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry. DEXA scans are most often used to diagnose osteoporosis, a condition that often affects women after menopause but may also be found in men. According to the International Osteoporosis Foundation (IOF), osteoporosis is greatly underdiagnosed and undertreated in Asia, even in the most high risk patients who have already fractured. Accroding to the IOF more than about 50% of all osteoporotic hip fractures will occur in Asia by the year 2050
A DEXA is a special form of x-ray technology that is used to measure bone loss. Osteoporosis involves a gradual loss of calcium, causing the bones to become thinner, more fragile and more likely to break. As well as offering screening for oesteoperosis, DEXA is also effective in assessing an individual's risk for developing fractures so that preventive interventions can be instituted in advance.
