The DXA scan is typically used to diagnose and follow osteoporosis. It is a means of measuring bone mineral density. Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology.
DXA scans are used primarily to evaluate bone mineral density. DXA scans can also be used to measure total body composition and fat content with a high degree of accuracy comparable to hydrostatic weighing.
