A DEXA scan, or Dual-Energy X-ray Absorptiometry scan, is a medical imaging test used to measure bone mineral density (BMD). It is commonly used to diagnose osteoporosis, ****ess fracture risk, and monitor changes in bone density over time. The scan involves lying on a table while a low-dose X-ray machine p****es over the body, typically focusing on the hip and spine. The procedure is quick, non-invasive, and painless, taking about 10-20 minutes. Results are compared to average BMD values to determine bone health. DEXA scans are crucial for early detection and management of bone-related conditions.
