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.
DEXA body composition and bone density analysis. Genetic testing. VO2 max assessment. ... Asthmatic patients, for example, might want a pulmonary function test after chatting with their doctor.
The calcium taken from your bones causes you to lose bone density. Bone loss also speeds up after menopause and can lead to weak, brittle bones. ... For example, menopausal hormone therapy may ...
For example, research shows that ... (DEXA) scan. Research shows that methods of determining body fat that consider waist circumference may be better than BMI at evaluating metabolic and ...
A DEXA scan requires medical supervision by a radiologist. Total body scans using DEXA give accurate and precise measurements of body composition, including bone mineral content (BMC), bone mineral density (BMD), lean tissue mass, fat tissue mass, and fractional contribution of fat.
