Radiographic absorptiometry: A simple method for determination of bone mass

Abstract: Bone mass measurements have been shown to be useful determinants of the risk of development of osteoporotic fractures and may help identify individuals who are most likely to benefit from both primary and secondary prevention of osteoporosis. As standard bone density measurements are not available to all physicians, there is a need for a fast, inexpensive, and widely available technique to measure bone mass. Radiographic absorptiometry of the phalanges requires only routine radiography with processing of the f… Show more

“…In vitro studies show that this method provides an accurate and precise assessment of bone mass (19). Further results indicate a significant correlation with radial single-photon absorptiometry (SPA) and spinal and femoral dual-photon absorptiometry (DPA) measurements in vivo (20). However, it should be noted that numerous physical factors that influence the radiographic image may also affect photodensitometry .…”

“…In this method, a radiograph of a peripheral site, typically metacarpals and phalanges, is obtained placing a reference wedge of hydroxyapatite or aluminum close to the bone. BMD is then expressed relative to the density of this wedge material (45). Even if RA was limited to peripheral skeletal sites, the composite volume density and the composite area density derived by RA at the phalanges showed a good correlation with the standard measurements of BMD derived by DXA (r=0.69 and 0.68 respectively, at lumbar spine; r=0.63 and 0.67 respectively, at the femoral neck) (45).…”

However, RA was time consuming and results were strongly influenced by multiple factors including operator expertise, X-ray beam intensity and soft tissue thickness (43).…”

“…The technique has been described in detail earlier [21,26,28]. Briefly, fingers of the non-dominant hand and an aluminum wedge were radiographed with the available radiographic equipment at the site, using a non-screened pre-packed sealed industrial film by Kodak.…”

“…Among these techniques, phalangeal ultrasound [18], computed digital absorptiometry [19,20] and radiographic absorptiometry (RA) [21,22,23,24,25,26,27,28] have documented reasonable sensitivity and specificity, which were, however, not sufficiently good to replace DXA for the diagnosis of osteoporosis. Recently, we addressed the question of whether and how well radiographic absorptiometry of the phalanges predicted osteoporosis at the spine or hip (as diagnosed by DXA) and whether a two-step diagnostic strategy (using RA as the first line to identify patients with low bone mass and DXA as the second line to assess the diagnosis of osteoporosis and take the treatment decision) was cost-effective in postmenopausal women [25].…”
