A DEXA scan (Dual-Energy X-ray Absorptiometry) is an advanced and highly precise imaging test that measures bone mineral density (BMD) to assess bone strength and detect conditions like osteoporosis and osteopenia. Using two low-dose X-ray beams, the scan provides detailed images of areas such as the spine, hips, or sometimes the whole body, allowing doctors to evaluate bone loss and fracture risk with great accuracy. The procedure is quick, non-invasive, and painless, typically completed within minutes, and is widely recommended for postmenopausal women, older adults, or individuals at risk of bone diseases. Regular DEXA scans help monitor changes in bone density over time, guiding effective prevention and treatment plans for maintaining long-term bone health.
