Dual Energy X-ray Absorptiometry (DEXA) provides accurate measurements of whole and regional body composition (fat, bone and muscle tissue).
the gold standard test for measuring bone density; uses low energy x-ray to measure the quantity of bone
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.
the gold standard test for measuring bone density; uses low energy x-ray to measure the strength of bones
Dual energy X-ray absorptiometry (DXA, previously DEXA) is a means of measuring bone mineral density (BMD). Two X-ray beams with differing energy levels are aimed at the patient's bones. When soft tissue absorption is subtracted out, the BMD can be determined from the absorption of each beam by bone.
