bone densitometry
(redirected from Dual energy X-ray absorptiometry)

    Also found in: Acronyms, Wikipedia 0.02 sec.
bone densitometry,
any of several methods of determining bone mass by measuring radiation absorption by the skeleton. Common techniques include single-photon absorptiometry (SPA) of the forearm and heel, dual-photon absorptiometry (DPA) and dual-energy x-ray absorptiometry (DXA) of the spine and hip, quantitative computed tomography (QCT) of the spine and forearm, radiographic absorptiometry (RA) of the hand, and quantitative ultrasound (QU).
bone densitometry (bōnˑ den·si·tˑ·me·trē),
n test that determines bone density according to the radiation absorption rate of the skeletal structure being tested.
bone densitometry
The measurement of bone mass or density; the current methods—single-photon absorptiometry, dual-energy photon absorptiometry, dual-energy X-ray absorptiometry, are based on tissue absorption of photons derived from either a radionuclide or an X-ray tube; the latter are more accurate with shorter scan time.

Secondary analyses will examine (1) the effect of the therapy on the functional muscle-bone unit, (2) the impact of pubertal stage, physical activity, and disease characteristics on the response to the therapy, and (3) the sensitivity of traditional dual energy x-ray absorptiometry (DEXA) measures of BMD to treatment effects.
