DEXA, or Dual-Energy X-ray Absorptiometry, is a medical imaging technique primarily used to measure bone density. It helps assess the risk of osteoporosis and fractures by providing detailed information about bone health. The procedure is quick, non-invasive, and involves minimal radiation exposure. In addition to measuring bone density, DEXA can also evaluate body composition, including fat and muscle mass. This information is valuable for monitoring health and fitness, especially in individuals looking to manage their weight or improve their physical condition. DEXA scans are commonly used in clinical settings and research.
