DXA: Technical aspects and application

European Journal of Radiology, 2016
The key role of dual-energy X-ray absorptiometry (DXA) in the management of metabolic bone diseases is well known. The role of DXA in the study of body composition and in the clinical evaluation of disorders which directly or indirectly involve the whole metabolism as they may induce changes in body mass and fat percentage is less known or less ...

Reproducibility of DXA in Obese Women

Journal of Clinical Densitometry, 2002
Dual-energy X-ray absorptiometry (DXA) measurements were analyzed using two versions of software (Hologic V8.1a and V8.21) to compare the short- and long-term precisions of the measurements. Software V8.21 was designed by the manufacturer to better address magnification effects on estimations of soft tissue lean mass.

Ability of Peripheral DXA Measurement to Diagnose Osteoporosis As Assessed By Central DXA Measurement

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 ...

Trabecular and cortical bone involvement in rheumatoid arthritis by DXA and DXA-based 3D modelling

Osteoporosis International, 2020
Rheumatoid arthritis (RA) patients had a higher risk of developing low bone mineral density (BMD) or osteoporosis. RA patients on classic disease-modifying antirheumatic drug (c-DMARD) therapy showed significantly lower BMD than controls, while no significant differences in most parameters were found between RA patients receiving biological disease ...

Utility of DXA for monitoring, technical aspects of DXA BMD measurement and precision testing

Bone, 2017
Monitoring a patient's bone mineral density (BMD) is one of the main reasons for dual-energy X-ray absorptiometry (DXA) referral. It is widely recommended by clinical guidelines, and the accepted standard in practice for managing patients with osteoporosis and other disorders.

Reporting DXA Results

2007
Acquisition and accurate interpretation of bone densitometry scans in the pediatric patient are necessary first steps toward any clinical assessment process. The dual-energy x-ray absorptiometry (DXA) report fulfills the role of transmitting data clearly to the clinician.

Recent developments in DXA. Quality of new DXA/MXA-devices for densitometry and morphometry

European Journal of Radiology, 1995
The introduction of new devices demands the assessment of their capabilities in established terms. The accuracy, reproducibility and spatial resolution of in vitro (phantom) osteodensitometric and morphometric measurements of QDR 2000 Plus and EXPERT are presented. Design details of these DXA/MXA-devices are listed and discussed in combination with the

Evaluation of Sarcopenia by DXA

Clinical Reviews in Bone and Mineral Metabolism, 2016
There are four body composition phenotypes widely used to describe older adults: normal, sarcopenic, obese, and sarcopenic obese. In this paper, we will discuss how DXA can be used to quantify body composition and how DXA can identify patients with sarcopenia and sarcopenic obesity.

Periprosthetic DXA

2014
The extraordinary advances in bone density technology since the 1970s have enhanced the physician’s ability to detect and manage metabolic bone disease. In the last 25 years, due to an improvements in hardware and software of dual-energy X-ray absorptiometry (DXA) there has been increasing interest within the orthopaedic community in the noninvasive ...

HSA: Beyond BMD with DXA

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.
