Dual X-Ray Absorptiometry
What is Osteoporosis Testing (DEXA)?
 A woman's risk for hip fracture alone is equal to the combined risk of
developing breast, uterine and ovarian cancer. Osteoporosis is a painful
disabling disease which causes bones to become brittle. Like high blood
pressure, it is called the silent killer. Often we're not aware of it until we
fall and break a bone(s) or there are signs of curvature of the spine, back
pain and loss of height. Unfortunately, when this occurs it may be too late
and could become debilitating and disfiguring.
What is Osteoporosis Testing (DEXA)?
Osteoporosis testing, also known as bone densitometry, as a diagnostic test
is an important tool for measuring and assessing bone mass in terms of density,
the loss of which is the leading factor in the medical condition - osteoporosis.
This information obtained through bone density studies is used to determine
a risk factor for potential fracture, or to establish baseline information
in the treatment of osteoporosis.
What is Osteoporosis?
Osteoporosis is a common disease of the skeletal structure characterized
by a decrease in bone mass and density resulting in greater risk of weakness
and fracture in certain groups of individuals, especially post-menopausal
women. As many as one in three post-menopausal women can be affected, and
one in eight men due primarily to aging and longer life expectancy. Additional
contributing factors to the loss of mineral salts that give bone its hardness
and rigidity are: reduced physical activity, smoking, alcohol consumption,
steroid therapy or chronic renal failure.
How does it work?
 The bone density test is a simple and painless, and takes approximately
five to ten minutes to perform. You will be asked to lie still on a table
while a movable arm passes over the area to be tested (e.g. arms, spine or
hips).
This test will measure your bone mineral density or bone mass. The the computer
will compare your results with a reference population whose age, sex and
racial background are similar to yours.
A bone density test requires no special preparatory drinks, medications,
or injections.
The radiologist will study the films and send a report to your physician
who will provide you with the results.
