Dual-energy projection methods have been used over the past decade for non-invasive measurement of bone. Dual-photon absorptiometry (DPA) using a Gd radionuclide source is used clinically in Cited by: Several case series document increased areal bone mineral density (aBMD) as measured either by single photon absorptiometry or dual-energy X-ray absorptiometry. 17,– While aBMD is increased at all skeletal sites, this increase is most marked at the lumbar spine, comprised of predominantly trabecular bone. 17, Hypoparathyroidism also. absorptiometry: [ ab-sorp″she-om´ĕ-tre ] in radiology, the measurement of the degree to which the radiation emitted by a radioisotope is completely dissipated within a tissue. dual energy absorptiometry (DEXA) an imaging technique that uses two low-dose x-ray beams with different levels of energy to produce a detailed image of body components;. Dual-energy X-ray absorptiometry (DXA) is indispensable for clinical practice in osteoporosis. DXA is the reference method for measuring bone mineral density (BMD) at the lumbar spine and proximal femur. However, bone strength mostly reflects the integration of bone density and bone quality. BMD accounts for only 70% of bone by:
Single-and Dual-Photon Absorptiometry Techniques for Bone Mineral Analysis Linda M. Thorson and Heinz W. Wahner Mayo Clinic and Mayo Foundation, Rochester, Minnesota This article on bone mineral analysis is the third of the con tinuing education series. After reading this paper, the reader shouldCited by: Background: Bone mineral density (BMD) measurements are frequently performed repeatedly for each patient. Subsequent BMD measurements allow reproducibility to be assessed. Objective: To examine the reproducibility of BMD by dual energy x ray absorptiometry (DXA) and to investigate the practical value of different measures of reproducibility in a group of postmenopausal by: The potential of dual-photon absorptiometry (DPA) for noninvasive bone measurements was originally reported by Reed () and by Cameron and Sorenson (). Dunn et al. () developed the dual-photon method for measuring the bone mineral content in the hip. Keywords Bone Mineral Density Author: Alan L. Huddleston. Whole-body dual-energy X-ray absorptiometry (DEXA, DXA), also called dual photon absorptiometry (DPA), and bioimpedance analysis (BIA) are both cost-effective and sufficiently accurate .Author: Jun Kyun Choi.
Dual X-ray absorptiometry and laser technique (DXL) in the area of bone density studies for osteoporosis assessment is an improvement to the DXA Technique, adding an exact laser measurement of the thickness of the region addition of object thickness adds a third input to the two x-ray energies used by DXA, better solving the equation for bone and excluding more efficiently these Purpose: bone density studies for osteoporosis assessment. Bone mineral content of different areas of the skeleton was measured by dual photon absorptiometry in 20 children with juvenile rheumatoid arthritis (JRA) and compared to 20 age and sex matched. Abstract. 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 absorptiometry. Dual Photon Absorptiometry synonyms, Dual Photon Absorptiometry pronunciation, Dual Photon Absorptiometry translation, English dictionary definition of Dual Photon Absorptiometry. Several techniques are used for measuring bone mass or bone mineral density: dual photon absorptiometry, dual energy x-ray absorptiometry and quantitative.
