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 ...

Recently, there has been a renewed interest in the detection and treatment of osteoporosis. This paper is a review of the merits and limitations of the various noninvasive modalities currently available for the measurement of bone mineral density with special emphasis placed upon the nuclear medicine techniques of single-photon and dual-photon ...

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'.

[Applications and results of photon absorptiometry].
Minerva endocrinologica, 1992Bone mineral content (CMO, mg/cm2) was measured at the distal radius by dual photon absorptiometry (DPA, I125, Am241) in 1.161 women (w), aged 20-87 years. Women were subdivided into different groups according to the presence and duration of menopause. For gross evaluation of spinal osteoporosis (OP), the results of spinal X-rays were graded as follows:

[Double photon absorptiometry in renal osteodystrophy].
Wiener klinische Wochenschrift, 1990Bone mineral content (BMC) of the lumbar spine (L2-L4), femoral neck, Ward's triangle and the trochanteric region was measured in 52 consecutive patients on maintenance haemodialysis. In the whole group the median BMC value as percentage of sex- and age-matched normal means was significantly decreased only in Ward's triangle (91.7%; p less than 0.02 ...

Precision of dual photon absorptiometry measurements.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1986One of the important uses of bone absorptiometry is to examine the rate of bone mineral change in order to evaluate therapy and to identify individuals who need therapy. Generally, this involves comparing the difference between two scans obtained months to years apart.
