DXA scans are conducted with the patient lying on a table while a scanner arm passes over their body. The machine emits low-energy X-rays that are absorbed differently by bone and soft tissue. This information is used to calculate bone mineral density (BMD) and body composition. The DXA scan provides a detailed image of the body, with different regions segmented for analysis. It measures BMD in grams per square centimeter (g/cm²) at various skeletal sites, including the spine, hip, and forearm. Additionally, DXA provides measurements of body composition such as lean body mass & fat mass. These measurements help diagnose osteoporosis as well as monitor changes in body composition over time.
