Dual-energy X-ray absorptiometry versus single photon absorptiometry of the radius [PDF]
Calcified Tissue International, 1991 Radial diaphyseal bone mineral density (BMD) was measured at the standard one-third site by dual-energy X-ray absorptiometry (DEXA) and by 125I single photon absorptiometry (SPA) in 70 consecutive subjects, aged 12-86 years, with metabolic disorders of the skeleton. Each patient was measured once by the DEXA (Hologic QDR-1000) instrument and four times

Technical Standardization for Dual-Energy X-Ray Absorptiometry
Journal of Clinical Densitometry, 2004Clinical applications of dual-energy X-ray absorptiometry (DXA) should be updated periodically to address new technologies and inconsistencies in the use of existing technologies. The 2003 Position Development Conference of the International Society for Clinical Densitometry addressed issues regarding hip and forearm regions of interest (ROIs ...

The British Journal of Radiology, 1998
An evaluation of the Osteoscan peripheral dual energy X-ray absorptiometer (pDXA) was carried out to compare its performance with those of a single photon absorptiometer (SPA) (Molsgaard Medical ND1100A) and a dual energy X-ray absorptiometer (DXA) (Lunar DPX alpha) of the spine or femur.

Calcified Tissue International, 1995
The purpose of this study was to determine the efficacy of using bone mineral measurements of the calcaneus to evaluate osteoporosis. Dual energy X-ray absorptiometry (DXA) of the calcaneus was compared with posteroanterior lumbar absorptiometry (DXA) and vertebral quantitative computed tomography (QCT) measurements in 171 white women (78 normal and 93

Dual-energy X-ray absorptiometry and body composition
Nutrition, 1996This review describes the advantages and limitations of dual-energy absorptiometry (DXA), a technique that is widely used clinically to assess a patient's risk of osteoporosis and to monitor the effects of therapy. DXA is also increasingly used to measure body composition in terms of fat and fat-free mass.

Indications and Reporting for Dual-Energy X-Ray Absorptiometry
Journal of Clinical Densitometry, 2004Although dual-energy X-ray absorptiometry (DXA) is widely used to measure bone mineral density (BMD), there are few guidelines regarding indications for testing in populations other than postmenopausal women or for reporting the results from DXA studies. At the 2003 Position Development Conference of the International Society for Clinical Densitometry,

Dual-energy X-ray absorptiometry pitfalls in Thalassemia Major
Endocrine, 2019Low mineral mass and reduced bone strength with increased fracture risk are the main causes of morbidity in Thalassemia Major (TM). The pathogenesis is multifactorial and includes ineffective erythropoiesis with medullary expansion, multiple endocrine dysfunctions, direct iron bone deposition, deferoxamine-induced bone dysplasia, and reduced physical ...

Suspension criteria for dual energy X ray absorptiometry
Radiation Protection Dosimetry, 2012The use of dual-energy X-ray absorptiometry (DXA) units primarily for the assessment of fracture risk and in the diagnosis of osteoporosis is ubiquitous in Europe and ever-expanding in its implementation worldwide. DXA is known for its reported low radiation dose and precision in the determination of bone mineral density.

Dual Energy X-Ray Absorptiometry and Its Clinical Applications
Seminars in Musculoskeletal Radiology, 2002Bone density scans using the technique of dual energy X-ray absorptiometry (DXA) are widely seen as having an essential role in the evaluation of patients at risk of osteoporosis. DXA scans of the spine and hip are the most useful because fractures at these sites result in the greatest impairment of quality of life.
