How does BMD work?

A BMD test is a non-invasive diagnostic procedure that measures the density of minerals (such ascalcium) in bones using a special X-ray, Dual-energy X-ray absorptiometry (DEXA). This methodology uses two different X-ray beams to estimate bone density in your spine and hip and can measure as little as 2% of bone loss per year strength of your bones. The procedure is fast, painless and uses very low doses of radiation to measure BMD and provides valuable information for estimation of the strength of your bones.
