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