Dual-energy X-Ray Absorptiometry (DEXA) Scan
About the Scan
A dual x-ray absorptiometry, or DEXA scan, is a scan that uses x-rays to measure your bone density, bone health, and full body composition with clinical-grade accuracy.
It provides a more accurate picture of your muscle, fat, and fitness compared to just your weight or BMI.
It can also diagnose low bone mass (called osteopenia) or osteoporosis before fractures occur.
Based on the results of your DEXA scan, your provider will propose treatments to keep your bones stronger, such as specific supplements or dietary changes, medications, and changes in lifestyle/exercise habits.
Research
Current research advocates for DEXA scans as “the gold standard for diagnosing osteoporosis”¹.
Osteoporosis is considered to be a public health concern and serious disease due to reduced bone density and increased fragility. There are often no symptoms until after a bone is broken².
