Dual-energy X-ray absorptiometry (DXA or DEXA) is a medical imaging technique primarily used to measure bone mineral density (BMD). It is considered the gold standard for diagnosing osteoporosis and assessing fracture risk. DXA works by using two different energy levels of X-ray beams to scan the body, typically focusing on the lower spine and hip, which are common sites for osteoporotic fractures.
