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.

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.
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.
You can calculate how much body fat you have in a few ways — such as with skinfold measurements, waist circumference measurements or a dual-energy X-ray absorptiometry (DEXA) scan.
“This can be done easily at home by using a biometric scale or can be monitored by using an annual DEXA scan ordered by a healthcare provider. This scan is also commonly used to track bone ...
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 bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis).
