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 attempting 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.

Your doctor will do a bone density test to see how strong or weak your bones are. A common test is a central dual-energy x-ray absorptiometry (DXA). A DXA is a special type of x-ray of your bones.
The improvement to DXA with DXL is that, for each pixel scanned by DXA, the exact thickness of the measured object is also measured using lasers. The DXL results allow for a more accurate estimation of bone density by using three separate inputs (low and high x-ray energies plus thickness) rather than two for each pixel in the measuring region.
Specific patient populations might benefit from specialized tests, like the DEXA body composition (i.e. women after menopause who typically lose bone density). Certain symptoms might prompt some ...
A 3-ounce serving of sockeye salmon nearly meets your daily vitamin D needs while also delivering a hearty dose of omega-3 ... magnesium and phosphorus. Calcium is essential for bone density ...
High intensity and high impact training is shown to be extremely beneficial in improving bone health and the most effective in improving, maintaining, bone density in the lower spine and femur. Although these types of exercises are safe for postmenopausal women, there still may be a need for supervision and precautionary measures. [126]
