WebSingle-photon absorptiometry (SPA) uses a single-energy beam usually passed through the wrist to provide a quantitative measurement of bone mineral and trabecular bone. Dual-photon absorptiometry measures BMD by the absorption of a dichromatic beam by bone material, and has limited usefulness in monitoring BMD changes. In current practice, these WebSingle photon absorptiometry is the first quantitative analysis method used in the diagnosis of osteoporosis. To evaluate bone quality, bone mineral content (BMC) and bone …
WebDual-energy X-ray absorptiometry (DXA, or formerly DEXA) is a technique used to measure bone mineral density (BMD). The preferred regions for BMD measurement are lumbar … WebDual-energy X-ray absorptiometry (DXA) is a method developed originally for the measurement of bone density and mass. DXA can also be used to measure soft tissue composition. DXA can measure total and regional fat, bone mineral, and bone mineral-free lean components.
