Clinical Applications

  • Dual energy X-ray absorptiometry (DXA) 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.
