Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology. The DXA scan is typically used to diagnose and follow osteoporosis, as contrasted to the nuclear bone scan, which is sensitive to certain metabolic diseases of bones in which bones are trying to heal from infections ...
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, 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 centimetre of bone surface upon imaging.

The standard in bone mineral density scanning developed in the 1980s is called Dual X-ray Absorptiometry, known as DXA. The DXA technique uses two different x-ray energy levels to estimate bone density. DXA scans assume a constant relationship between the amounts of lean soft tissue and adipose tissue.
Medicare will cover bone density scans for a person who meets certain medical requirements, such as osteoporosis risk factors.
Dexa Scan (Bone density scan) [4] Treatment: Good diet, exercise, ... Osteoporosis is defined as a bone density of 2.5 standard deviations below that of a young adult.
Sam Mitchell, 50, from Gwaun-Cae-Gurwen, Neath Port Talbot, said despite her low-impact break and a family history of osteoporosis, she does not qualify for a scan to check her bone density.
Unlike most other common techniques for measuring BMD, a pQCT scan is able to measure volumetric bone mineral density, plus other measures such as the stress-strain index (SSI) and the geometry of the bone. DXA is only able to provide the areal bone mineral density. High-resolution peripheral quantitative computed tomography (HR-pQCT) is better ...
Eventually, when I did a bone density scan, the doctors saw that I also have osteoporosis. It wasn’t causing any pain or fractures, likely because it hadn't gotten too severe yet, and I wasn’t ...
