Photon absorptiometry of hydrocarbons
International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1986Abstract 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, 1985Abstract 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, 1979ABSTRACT 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, 1987Dual-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, 1989Bone 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, 1991Radial 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

Osteoporosis International, 1995
The aim of the present study was to evaluate a new device for measurement of forearm bone mass using the technique of single X-ray absorptiometry (SXA, DTX-100; Osteometer A/S, Rødovre, Denmark), and to compare the performance with the more traditional single photon absorptiometry (SPA, DT 100; Osteometer A/S, Rødovre, Denmark).

Rinsho hoshasen. Clinical radiography, 1990
BMC and BMD of the total body bone and lumbar spine were measured in normal control and patients with metabolic bone diseases by DPA (Dichromatic Bone Densitometer Model 2600, Norland corporation). Also, total body fat mass was measured in patients with obesity.

Total body composition by dual-photon (153Gd) absorptiometry
The American Journal of Clinical Nutrition, 1984The lean-fat composition (%FATR) of soft tissue and the mineral mass of the skeleton were determined in vivo using dual-photon (153Gd) absorptiometry (dose under 2 mrem). A rectilinear raster scan was made over the entire body in 18 subjects (14 female, 4 male). Single-photon absorptiometry (125I) measured bone mineral content on the radius. Percentage

Sensitivity of dual-photon absorptiometry in spinal osteoporosis
Calcified Tissue International, 1988Lumbar spine bone mass and density were measured with Dual photon absorptiometry (DPA) in 60 patients with crush fractures and 60 age-matched normal women. Short-term reproducibility of bone mineral density (BMD) was 1.3% in normal women and 2.5% in osteoporotic women; long-term reproducibility in normal women was 2.2%.
