DXA scans can also be used to measure total body composition and fat content with a high degree of accuracy comparable to hydrostatic weighing with a few important caveats. [18] [specify] From the DXA scans, a low resolution "fat shadow" image can also be generated, which gives an overall impression of fat distribution throughout the body. [19]
DXA scanners can be used to diagnose osteopenia or osteoporosis as well as to measure bone density over time as people age or undergo medical treatment or lifestyle changes. [ 23 ] Information from the DXA scanner creates a bone mineral density T-score by comparing a patient's density to the bone density of a healthy young person.
DXA scans assume a constant relationship between the amounts of lean soft tissue and adipose tissue. This assumption leads to measurement errors, with an impact on accuracy as well as precision. To reduce soft-tissue errors in DXA, DXL technology was developed in the late 1990s by a team of Swedish researchers led by Prof. Ragnar Kullenberg.
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.

A DEXA scan (which measures lean mass, but not specifically muscle, according to Dr. Neeland) or even an MRI can be the most accurate ways to measure this, but you can also try a scale that ...
At the hip, a DXA-equivalent T-score may be calculated for comparison to the WHO classification at the proximal femur as normal, osteopenia (T-Score < -1.0 and > -2.5) or osteoporosis (T-Score < -2.5). [17] This T-Score may also be used for fracture risk probability calculation in the WHO FRAX tool [18] with "T-Score" as the appropriate DXA ...

A new report from the United States Department of Agriculture (USDA) suggests that beans and legumes are healthier proteins than lean meat: here's why.
