Quantitative dual-energy radiographic absorptiometry of the lumbar spine: in vivo comparison with dual-photon absorptiometry.

Radiology, 1989
Quantitative dual-energy radiographic absorptiometry (DRA) and dual-photon absorptiometry (DPA) were compared to determine the best means of assessing bone density. Both methods were used to evaluate the lumbar spine in 107 women (aged 35-84 years [mean,

Total body bone mineral in vivo by dual photon absorptiometry. II. Accuracy.

Clinical Physiology, 1984
We investigated the accuracy of total body mineral (TBBM) measured by dual photon absorptiometry (1 Ci 153Gd source, 44 and 100 KeV) using skeletons, soft tissue equivalent materials and whole cadaver extremities.

Triple-Photon Energy Absorptiometry in the Measurement of Bone Mineral

Acta Radiologica, 1988
The 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.

Dual-Photon Absorptiometry

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- and dual-photon absorptiometry in osteoporosis and osteomalacia

Seminars in Nuclear Medicine, 1987
Single- 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 ...

Heterotopic Ossification Effect on Dual-Photon Absorptiometry of the Hip

Clinical Nuclear Medicine, 1990
Dual-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.

Measurements of Bone Mineral by Photon Absorptiometry [PDF]

open access: possible, 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 ...

Effects of nonmineral tissues on measurement of bone mineral content by dual-photon absorptiometry.

Medical Physics (Lancaster), 1990
Computer simulations were performed to investigate the effects of nonmineral tissue (overlying soft tissue and nonmineral components of bone) on the measurement of bone mineral content by dual-photon absorptiometry (DPA).

Broadband ultrasonic attenuation in the os calcis and single photon absorptiometry in the distal forearm: a comparative study.

Clinical Physics and Physiological Measurement, 1986
The measurement of broadband ultrasonic attenuation (BUA) in the os calcis has been described recently but the method has not been compared with other non-invasive techniques for the assessment of bone mass. We have compared the measurement of BUA in the

Bone mineral density in children with Down's syndrome detected by dual photon absorptiometry.

Nuclear medicine communications, 1992
Bone mineral density (BMD) in ten children with Down's syndrome (seven boys, three girls; aged 10-16 years) was measured by dual photon absorptiometry (DPA) using an M&SE OsteoTech 300 scanner.
