Radiogrammetry and Radiographic Absorptiometry
1998This chapter addresses the methods of radiogrammetry (translated freely as “measuring dimensions on radiographs”) and radiographic absorptiometry (“measuring the X-ray absorption on radiographs”). Both techniques have been used widely in the past, and especially the latter continues to be used in the present as a straightforward, relatively simple and ...

Dual photon absorptiometry of the proximal tibia
Calcified Tissue International, 1989Bone mineral content (BMC) and bone mineral density (BMD) of the proximal tibia were determined by dual photon absorptiometry on 44 women, aged 23-87 years. The area of the tibia measured was a 2.01 cm region immediately distal to the medial and lateral tuberosities.

Dual-energy X-ray Absorptiometry
Journal of Clinical Densitometry, 2017Bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) is the most commonly used method to assess fracture risk. DXA utilizes two different energy X-rays to calculate BMD and, by comparison to a young normative database, the T-score.

Dual-photon absorptiometry of the proximal tibia
Archives of Orthopaedic and Traumatic Surgery, 1987Dual-photon absorptiometric bone-mineral assay, penetration tests, and axial compression tests of the proximal tibial epiphyses were carried out in 18 human cadaver knees. The reproducibility of bone mineral assay was within +/- 12% (95% tolerance limits).

OSTEOPOROSIS IN HYPERTHYROIDISM ESTIMATED BY PHOTON ABSORPTIOMETRY
Acta Endocrinologica, 1979ABSTRACT The degree of osteoporosis in hyperthyroidism before and during treatment with carbimazole was studied by photon absorption technique of the right forearm and calcaneus. In addition serum total calcium, serum ionized calcium, serum phosphorus and serum alkaline phosphatase were determined.

Radiology, 2000
With a standard, image-intensifier-based, digital radiographic system, high-spatial-resolution images of the hand were acquired for analysis of phalangeal bone mineral density with dual x-ray absorptiometry (DXA). Results with phalangeal DXA had precision of plus or minus 0.67% and accuracy of 4.1% and correlated well with those with radiographic ...

Rinsho hoshasen. Clinical radiography, 1990
BMC and BMD of the total body bone and lumbar spine were measured in normal control and patients with metabolic bone diseases by DPA (Dichromatic Bone Densitometer Model 2600, Norland corporation). Also, total body fat mass was measured in patients with obesity.

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 ...
