Bone Densitometry
(DEXA)
NYHQ now offers DEXA (Dual Energy
X-ray Absorptiometry) scans in the new MRI suite. A DEXA
is an exam which allows your doctor to determine if you
are risk for a fracture. Low bone density puts you at higher
risk. Exam information will help you and your doctor decide
the best course of action for your bone health.
Using small amounts of two different
radiation levels a bone densitometer creates images of the
spine and the hips. After comparing the way your body absorbs
the two radiation energy levels a computer determines how
much bone mineral is present. If the bone mineral level
is very low it is called osteoporosis. Osteoporosis is a
condition where bones become weak, sometimes to the point
of fracture. Weakening may be caused by aging or a combination
of factors. Often there are no obvious signs of osteoporosis
until a fracture occurs or a large amount of bone strength
has been lost. |
