Dual-energy X-ray Absorptiometry, DXA, DEXA.
DEXA uses X-rays to measure the strength, density and mineral content of bone. DEXA is most often used
to diagnose osteoporosis, a condition that often affects women after menopause but may also be found
in men. Osteoporosis involves a gradual loss of calcium, as well as structural changes, causing the bones
to become thinner, more fragile and more likely to break.
DEXA is also effective in tracking the effects of treatment for osteoporosis and other conditions that
cause bone loss. DEXA can also access an individual's risk for developing fractures.
