DEXA Bone Density Scan
A DEXA bone density scan measures hip and spine mineral density—the standard test to screen osteoporosis and track treatment over time.
A DEXA bone density scan uses low-dose X-rays to estimate bone mineral density at the hip and lumbar spine—the standard test for osteoporosis screening and treatment monitoring. The exam is quick, non-invasive, and compares results to young-adult and age-matched references.
Prepare by avoid calcium supplements the morning of the scan if your clinic requests it.
Common questions
-
Does a DEXA scan expose you to much radiation?
DEXA uses very low radiation—often less than a day of natural background. Still, only scan when clinically indicated, not for curiosity alone.
