The Noninvasive Determination of Bone Mineral Content by Photon Absorptiometry
Archives of Pediatrics & Adolescent Medicine, 1982The human endoskeleton is composed of a collagen-containing organic matrix upon which is deposited a crystalline mineral phase. The strength and structural properties of bone depend on its resiliency, tensile properties, and compressive strength. Bone weakness thus develops whenever there are changes in the formation of the organic matrix, in the ...

Body composition by photon absorptiometry.
Canadian journal of sport sciences = Journal canadien des sciences du sport, 1990Whole-body dual photon measurements of body composition were made in 9 controls, 15 athletes and 5 patients with eating disorders. Measurements of lean body mass, mineral mass and fat mass were accurate. Lean body mass and fat mass were measured with reliabilities of about 0.8 kg while for total body bone mineral mass, the reliability was about 60 g ...

Measurement of bone mineral content in human vertebrae and hip by dual photon absorptiometry.
Radiology, 1980An instrument for clinical measurement of bone mineral content in the axial skeleton was constructed. Components include a modified dual probe scanner, a PDP-11 computer, a 153Gd source, and a NaTI) detector.

Estimation of Bone and Skeletal Weight by Direct Photon Absorptiometry
Investigative Radiology, 1971The direct photon (125I) absorptiometric method for radiologic measurement of bone was used to examine the intercorrelations among determinations at various sites on the human ulna, radius, humerus and femur.

Physics in Medicine and Biology, 1991
Theoretical and experimental studies have been conducted to explore the possibilities of triple photon energy absorptiometry in the measurement of bone mineral content. The purpose of this technique is to correct the measured bone mineral density for fat

Demineralization in cystic fibrosis detected by direct photon absorptiometry
The Journal of Pediatrics, 1979Bone mineral content, bone width, and their ratio were measured in patients with cystic fibrosis (CF) using monoenergetic photon absorptiometry. Serial measurements of the radius and ulna were made in 27 patients with CF and were compared with 968 age-matched controls. Demineralization was found in 37% of the boys and 63% of the girls.

The crossover correction in dual photon absorptiometry with 153Gd
Physics in Medicine & Biology, 1982Considers one aspect of the methodology of dual photon absorptiometry which is specifically important when using 153Gd and which affects the absolute determination of bone mineral content. This is the contribution to the 44 keV energy window from the 100 keV energy caused by Compton events within the crystal and scatter within the patients.

Photon absorptiometry of bone after successful renal transplantation
The British Journal of Radiology, 1977Photon absorptiometric measurements of the right lower femur were carried out at regular intervals of one to three months in 58 recipients of renal transplant. (1) During the first six months after transplant 57% showed a significant and abnormal rate of loss of bone mineral (mean 11.7% per year.

Monitoring fluoride therapy in osteoporosis by dual photon absorptiometry
Bone, 1987Dual photon absorptiometry (DPA) was used to evaluate changes in bone mineral mass in 108 osteopenic patients. Ninety were treated with fluoride and 18 served as controls. All osteopenic patients and 9 of the controls took calcium and vitamin D supplements. In 16 women estrogens were combined with the fluoride therapy.

Bone mineral analysis of the rat femur by direct photon absorptiometry
Calcified Tissue International, 1981This report describes a method using direct photon absorptiometry (DPA) for determination in vivo of the bone mineral content to bone width ratio (BMC/W) in the rat femur. A significant correlation was noted between measurements by DPA and whole femur dry weight and ash weight.
