Precision of dual-photon absorptiometry

Calcified Tissue International, 1988
Precision of dual-photon absorptiometry (DPA) measurements was determined in a lumbar spine phantom and in humans. Approximately half of the measurements were made before and half after a 153gadolinium source change. The phantom was measured with different amounts of acrylic, which simulates human soft tissue, in order to evaluate the influence of body

Photon absorptiometry of hydrocarbons

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1986
Abstract Measured and parametrised values of the attenuation coefficients of several hydrocarbons having a hydrogen-to-carbon weight ratio in the range from 0.05 to 0.16 and for photon energies 33, 75, 145, 279 and 662 keV are presented. The values are compared and possible trends and applications discussed.

Photon absorptiometry of bone and bone standards

The International Journal of Applied Radiation and Isotopes, 1985
Abstract Measured and parametrised values of the attenuation coefficients of bone and several bone standards are presented for the photon energies 33, 75, 145, 279 and 662 keV. The values are compared, inadequacies are highlighted and possible new formulations are discussed.

OSTEOPOROSIS IN HYPERTHYROIDISM ESTIMATED BY PHOTON ABSORPTIOMETRY

Acta Endocrinologica, 1979
ABSTRACT The degree of osteoporosis in hyperthyroidism before and during treatment with carbimazole was studied by photon absorption technique of the right forearm and calcaneus. In addition serum total calcium, serum ionized calcium, serum phosphorus and serum alkaline phosphatase were determined.

Dual-photon absorptiometry of the proximal tibia

Archives of Orthopaedic and Traumatic Surgery, 1987
Dual-photon absorptiometric bone-mineral assay, penetration tests, and axial compression tests of the proximal tibial epiphyses were carried out in 18 human cadaver knees. The reproducibility of bone mineral assay was within +/- 12% (95% tolerance limits).

Dual photon absorptiometry of the proximal tibia

Calcified Tissue International, 1989
Bone mineral content (BMC) and bone mineral density (BMD) of the proximal tibia were determined by dual photon absorptiometry on 44 women, aged 23-87 years. The area of the tibia measured was a 2.01 cm region immediately distal to the medial and lateral tuberosities.

Dual-energy X-ray absorptiometry versus single photon absorptiometry of the radius

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
