Bone Mineral Densitometry
Bone density or bone mineral density (BMD) is the amount of bone mineral in bone tissue.
The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimeter of bone surface upon imaging.
Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today’s established standard for measuring bone mineral density (BMD). An x-ray exam helps doctors diagnose and treat medical conditions.
