(dual energy X-RAY absorptiometry): a type of bone mineral density radiologic examination using x-ray absorption; see also qCT
ual nergy -ray bsorptiometry. A means of measuring bone density to detect osteoporosis.
A low-intensity Xray used to measure bone density/osteoporosis.
Dual energy X-ray absortiometry. A method used to estimate total body fat and percent of body fat. Potential disadvantages include whole body radiation and the long time required for scanning while the subject lies on a hard table.
Dual Energy X-Ray Absorptiometry. Highly reliable means of measuring bone mineral density using very small amounts of radiation.
This term stands for “dual-energy x-ray absorptiometry.” DEXA is a form of total-body x-ray, which is used to determine body composition. This is probably the most accurate method available for measuring bodyfat, lean body mass, bone mineralization, and body water content. This is a very expensive procedure; however, it's an important part of quality clinical trials.
Dual Energy X-Ray Absorptiometry. the gold standard test for measuring bone density; uses low energy x-ray to measure the quantity of bone
Dual Energy X-ray Absorptiometry. Dual Energy X-ray Absorptiometry (DEXA) provides accurate measurements of whole and regional body composition (fat, bone and muscle tissue).
Dual Energy X-ray Absorptiometry. A non-invasive method for determining bone mineral content (which correlates with the amount of calcium in the skeleton). This type of exam uses 2 low dose x-ray beams of different energies. This test is quick and painless and can calculate total body fat and lean body mass, in addition to estimating bone mineral content. Clinically, it is used in diagnosing osteopenia and osteoporosis.

imaging technique that uses a very low dose of radiation to measure bone density for the diagnosis of osteoporosis.
