Bone, 2007
The measurement of bone mineral density is a surrogate for the measurement of bone strength. Bone strength is comprised of many components including, but not limited to bone architecture, geometry, cortical porosity and tissue mineralization density.

30 years of DXA technology innovations
Bone, 2017As the successor of Dual Photon Absorptiometry (DPA), Dual X-ray Absorptiometry (DXA) has seen 30years of continuous technological innovations. Implementation of measures for standardization and quality assurance made DXA a reliable and clinically useful approach.

Journal of Clinical Densitometry, 2004
In order to evaluate the utility of peripheral measurement of bone mineral density (BMD) in the diagnosis of osteoporosis, we measured BMD at the spine and femoral neck with central dual-energy X-ray absorptiometry (DXA), at phalanx with AccuDXA (Schick) as well as proximal and distal forearm with pDXA (Norland) in 835 women ranging in age from 20 to ...

Relationship Among MRTA, DXA, and QUS
Journal of Clinical Densitometry, 2004Dual-energy X-ray absorptiometry (DXA) and quantitative ultrasound (QUS) are the accepted modalities for the evaluation of fracture risk in the clinical setting. However, neither method provides a direct measurement of bone mechanics. In this study, we investigated a prototype device, known as a mechanical response tissue analyzer (MRTA), which ...

Pediatric DXA bone measurements.
Pediatric endocrinology reviews : PER, 2006Dual-energy x-ray absorptiometry (DXA) has become the most commonly employed technique worldwide for assessment of bone mineral content in adults and children. DXA interpretation in children is more complex because bone dimensions are highly dynamic. Pediatric use of DXA can be used to identify risk of adult osteoporosis.

DXA parameters: Beyond bone mineral density
Joint Bone Spine, 2013Dual-energy X-ray absorptiometry (DXA) is the reference standard for measuring bone mineral density (BMD) to diagnose osteoporosis. However, BMD measurement alone does not reliably predict the fracture risk. DXA can be used to assess other parameters (e.g.

Performing a DXA PA Lumbar Spine, Proximal Femur, or Forearm DXA Study
2012The most commonly studied regions of the skeleton remain to be the PA lumbar spine, proximal femur, and forearm in spite of the development of software applications that allow measurement of virtually any skeletal region. The manufacturers of DXA devices provide instructions for patient positioning for the different types of DXA studies that can be ...

2009
Densitometry has primarily been a quantitative measurement technique. The first skeletal images from a densitometer, as seen in Fig. 2-7 in an earlier chapter, were only vaguely reminiscent of the actual bone. The poor image quality had little effect on the ability to quantify the bone density, which was the primary purpose of the various techniques ...

Nihon rinsho. Japanese journal of clinical medicine, 2006
In this article, an outline of dual energy X-ray absorptiometry (DXA), quantitative ultrasound (QUS), and radiogram, and their characteristics, problems, and assessment of osteoporosis in the elderly were reviewed. It is well known that both DXA and QUS are available to risk assessment of fractures. However, because lumbar bone mineral density (BMD) is
