Dual Photon Absorptiometry The Importance of Clinical Correlation
Clinical Nuclear Medicine, 1988Dual photon absorptiometry is a reliable method of assessing bone mineral density. However, distortions of bony architecture, which may not be evident from the low-resolution images provided, can complicate the evaluation and lead to misleading findings. A case is presented which describes the importance of clinical and radiographic correlation.

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.

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 ...

Single-photon absorptiometry (SPA) was first described by Cameron and Sorenson (1963) in an effort to overcome the problems inherent in the use of film densitometry. The basic configuration for the single-photon systems commercially available today was introduced in 1972 (Mazess and Cameron, 1972).

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 ...

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

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%.

Intra-laboratory variations using dual-photon absorptiometry
Physics in Medicine and Biology, 1983A letter by R.B. Mazers et al. (see ibid., vol.28, no.6, p.747-8, 1983) is commented on. That letter commented on a scientific note by the authors (see ibid., vol.27, p.1515-21, 1982) in which the authors stated that there were intra-laboratory differences between cross-sectional studies of vertebral bone mineral content in normal women as measured by ...

Dual-photon absorptiometry (spine mineral content measurement)
Physics in Medicine and Biology, 1983A report by M.A. Smith and P. Tothill (see ibid., vol.27, p.1515-21, 1982) is commented on. That report suggested, without evidence, that intra-laboratory variation in measurements of the bone mineral of the spine may be due to a technical problem termed 'crossover'.
