DEXA
DEXAabbr. dual-energy x-ray absorptiometryTranslationsDEXA
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; used primarily to measure bone mineral density.dual photon absorptiometry measurement of bone mineral content in the axial skeleton, particularly the lumbar spine, by comparing transmission of the two separate photoelectric energy peaks emitted by gadolinium 153 through both soft and bone tissues.DEXAAbbreviation for dual-energy x-ray absorptiometry.DEXAabbr. dual-energy x-ray absorptiometrydual-energy X-ray absorptiometry A technique using two different X-ray beams to estimate bone density in vertebrae and hip, which is the most accurate way to measure bone mineral density. Strong, dense bones allow less of an X-ray beam to pass through them; the amounts that each beam are blocked by bone and soft tissue are compared to each other.
Pros
DEXA can measure as little as 2% bone loss/year; it is fast and uses very low doses of radiationDEXA Abbreviation for dual-energy x-ray absorptiometry. DEXA
