The Use of Photon Absorptiometry in the Diagnosis of Renal Osteodystrophy
Radiology, 1973By using a 125I collimated point source to measure bone mineral, 700 measurements were obtained from the cortical bone of the lower arm in 303 patients with renal failure representing every stage of the disease. Of these patients, 123 had received transplants.

An evaluation of dual-energy X-ray absorptiometry and comparison with dual-photon absorptiometry
Osteoporosis International, 1992Dual-photon absorptiometry (DPA) is a well-established procedure for measuring bone mineral density (BMD). Recently, dual-energy X-ray absorptiometry (DXA) has become available, which has the ability to measure BMD both regionally and in the total body (TB). We have evaluated the in vivo and in vitro precision of a DXA instrument and compared it with a

Photon absorptiometry, bone densitometry and the challenge of osteoporosis
Physics in Medicine and Biology, 2006During the lifetime of Physics in Medicine and Biology, osteoporosis has been recognized as the cause of a major health burden for societies, particularly within developed countries. The health detriment is associated with the consequences of bone fractures and the subsequent increases in morbidity and mortality.

Dual-photon Gd-153 absorptiometry of bone.
Radiology, 1985Dual-photon absorptiometry with gadolinium 153 was used to measure the mineral content of lumbar vertebrae in cadavers, excised vertebrae with marrow, and dry, marrow-free vertebrae. The error introduced by the surrounding soft tissue of cadavers was 3%, and the error in determining mineral mass or density in excised vertebrae was about 5%.

Triple-Photon Energy Absorptiometry in the Measurement of Bone Mineral
Acta Radiologica, 1988The feasibility of determination of bone mineral content using a triple-photon absorptiometric technique is presented. Using three different photon energies it is possible to correct the measured ‘bone mineral’ value for fat and lean soft tissue.

1988
The potential of dual-photon absorptiometry (DPA) for noninvasive bone measurements was originally reported by Reed (1960) and by Cameron and Sorenson (1963). The first equipment utilizing this technique was constructed by Reed and Atkinson (1965; Reed, 1966), and methods for measurement of the BMC of the lumbar vertebrae in vivo were subsequently ...

Heterotopic Ossification Effect on Dual-Photon Absorptiometry of the Hip
Clinical Nuclear Medicine, 1990Dual-photon absorptiometry (DPA) is now widely used to determine bone mineral density of the lumbar spine and hips. Because the resulting images are often not of sufficient resolution to identify many bone or soft tissue abnormalities that may influence results, clinical and radiographic correlation is necessary.

Single- and dual-photon absorptiometry in osteoporosis and osteomalacia
Seminars in Nuclear Medicine, 1987Single- and dual-photon absorptiometric methods have been used in the past to identify populations at risk for bone loss, to define the osteoporotic syndrome in terms of bone mass, and to evaluate treatment regimens to prevent bone loss. Technical improvements have made these procedures available for the nontraumatic measurement of bone mineral in the ...

Measurements of Bone Mineral by Photon Absorptiometry [PDF]
, 1987 The recognition of the socioeconomic impact of osteoporosis in our ageing population, with its associated morbidity and mortality from spinal, hip and radius fractures, has led to an increasing interest in bone mass and its measurement. As a result, several clinically tested methods are now available for diagnosing low bone mass, measuring the rate of ...

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
