This article is an introduction to dual X-ray absorptiometry (DXA), the most widely used method today for diagnosis of osteoporosis. DXA can be used to assess projective bone mineral density at the lumbar spine, the proximal hip, and the whole body as well as the skeletal periphery at the forearm, the hand, and the heel.

[Spinal biphotonic absorptiometry].
Revue du rhumatisme et des maladies osteo-articulaires, 1986Spinal biphotonic absorptiometry allows a quantitative investigation of bone mineralisation. The study of a control and an osteoporotic population allowed the definition of the fracture threshold independent of age and the curve of the variation in the mineral content with aging. A good correlation was observed with computed tomography. The criteria of

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 ...

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

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 ...

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).

Bone mass measurements are essential in the diagnosis of osteoporosis, the monitoring of its progression, and the evaluation of therapeutical responses. Among various methods of bone mass measurements, single- and dual-X-ray absorptiometry, SXA and DXA, have shown excellent fundamental performance.

Reversion : a New Procedure in Absorptiometry
Nature, 1948MANY metals form coloured complexes with dithizone, and the successful use of this reagent for estimating one of them in a mixture demands a careful selection of organic solvent, a rigorous control of pH and other variables such as duration of shaking, nature and amount of neutral salts present, the concentration of excess dithizone, and the ...
