Bone Densitometry

Bone density scanning, also called dual-energy x-ray absorptiometry (DXA or DEXA) or bone
densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DEXA is
today’s established standard for measuring bone mineral density (BMD).

DEXA is most often performed on the lower spine and hips. DEXA bone densitometry 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, 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.

The DEXA test can also assess an individual’s risk for developing fractures.
