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.

You should consider a vascular screening if you have risk factors for any vascular disorder. A family history of stroke, aneurysm, or Peripheral Artery Disease suggests the need for screening, often beginning in the 30s – particularly if other risk factors co-exist.
