| Bone
Densitometry (DEXA)
– Clinical
Applications |
|
|
|
|
 |
|
|
Dual
energy X-ray absorptiometry (DEXA) is used to determine
bone mineral density in the central skeleton; spine,
hip, and total body. It is very precise and is considered
the "gold standard" in determining bone
density for diagnosis and treatment follow-up for
osteoporosis. |
|
|
Bone
mass measurements predict a patient's future risk
of fracture. |
|
|
Clinical
circumstances in which bone density measurement
is appropriate |
|
|
|
For
risk assessment in perimenopausal or postmenopausal
women who are concerned about osteoporosis and willing
to accept intervention. |
|
|
In
women with X-ray findings that suggest the presence
of
osteoporosis. |
|
|
In
women beginning or receiving long-term steroid therapy. |
|
|
For perimenopausal or post menopausal women with
asymptomatic hyperparathyroidism, in whom evidence
of skeletal loss would result in hyperparathyroidectomy. |
|
|
In
women undergoing treatment for osteoporosis as a
tool for
monitoring the therapeutic response. |
