The early diagnosis of osteoporosis, before the occurrence of fractures, can only be made by means of bone density measurements [bone mineral density(BMD) tests] (Table 7.1). These measure bone density at various skeletal sites and thereby enable a prediction of risk of later fracture. A 10%...
Osteopenia : low bone density, like osteoporosis , but not as severe. Osteopenia has a bone density between 1 and 2.5 standard deviations below the reference (i.e., a T-score between −1.0 and −2.5), while osteoporosis has a T-score of ≤–2.5. Osteomalacia : the softening of the...
BACKGROUND: Although bone mineral density (BMD) testing to screen for osteoporosis (BMD T score, -2.50 or lower) is recommended for women 65 years of age or older, there are few data to guide decisions about the interval between BMD tests. METHODS: We studied 4957 women, 67 years of age...
·Osteoporosis isdefined asa fragility fracture orT-score≤ -2.5 when determined by lowest calculation from lumbar spine (at least 2 evaluable vertebrae), femoral neck, or total femur T-score. ·Osteopenia is low normal bone density that is not low enough to be osteoporosis, as defined byT-sco...

In view of evidence that corticosteroid use is an independent risk factor for fracture over and above bone mineral density, guidelines for intervention set a higher threshold than the World Health Organization figure ( -score=-1.5 rather than -2.5) for intervention with bone sparing treatment in ...
Trabecular bone score (TBS) is a grey-level textural measurement acquired from dual-energy X-ray absorptiometry lumbar spine images and is a validated inde
A noninvasive test called dual-energy X-ray absorptiometry (DEXA or DXA) can assess your bone density. It provides measurements called T-scores that may indicate osteopenia or osteoporosis. The scores also help determine your vulnerability to to bone fractures. A T-score ranging from -1 to -...
