Bone mineral density

Bone mineral density (BMD) is a measurement of the concentration in bone of minerals (mostly calcium and phosphate) that are vital for strong bones. A high bone mineral density indicates above-average amounts of calcium and phosphates in the bones, while a below-normal bone mineral density can indicate a loss of bone mass, possibly from osteopenia or osteoporosis.
