DXA (Dual-energy X-ray Absorptiometry) is a diagnostic test used to measure bone density. It is a tool used to detect and diagnose osteoporosis. DXA scans can help determine risk for fracture, as well as the rate of bone loss and response to osteoporosis treatments. DXA services are available at Lakes Region General Hospital and Franklin Regional Hospital.
A DXA exam takes approximately 10-15 minutes and is performed with the patient fully clothed. Scans allow for the detection of osteoporosis before a fracture occurs by determining the risk for fracture in the future. The rate of bone loss and response to osteoporosis treatments can also be determined with consecutive scans, typically done every one to two years.
Medicare may authorize a DXA scan every two years.
