A DEXA (Dual-Energy X-ray Absorptiometry) scan is a medical imaging technique used to measure bone mineral density (BMD). It involves using two X-ray beams at different energy levels to create detailed images of the bones, typically focusing on the spine, hip, and sometimes the forearm. The scan is quick, non-invasive, and exposes patients to minimal radiation. DEXA scans are crucial for diagnosing osteoporosis, assessing fracture risk, and monitoring changes in bone density over time. They are also used to measure body composition, including fat and lean body mass, providing valuable information for health and fitness assessments.
