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.

Decreased bone density. Inadequate calorie intake, along with low calcium and vitamin D intake, can increase the risk of bone fractures over time. Reduced metabolism.
Prior to the adoption of DXA, the most accurate method of estimating body fat percentage was to measure that person's average density (total mass divided by total volume) and apply a formula to convert that to body fat percentage. Since fat tissue has a lower density than muscles and bones, it is possible to estimate the fat content.
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.
Elevated low-density lipoprotein (aka “bad cholesterol”) The men also had elevated total cholesterol. Beyond this, 60 percent of the women in this group had an abdominal circumference of ...
Medicare covers bone density tests provided a person meets certain criteria for getting the scan. These criteria may include age and gender as well as personal medical history and risk factors ...
The BRI has proved effective as an index for identifying risk of death from different diseases, [3] disorders of metabolic syndrome, [4] [5] [7] liver disease, [6] cardiovascular diseases in association with sarcopenia, [8] and bone mineral density. [9]
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).
