Summary
A bone density scan, also known as dual-energy x-ray absorptiometry (DXA) or bone densitometry, is a form of x-ray technology used to measure bone loss. It is a quick and painless procedure that involves lying on an X-ray table and may not require any special preparations.

DEXA scans measure the mineral content in certain bones, such as the hip, spine and/or wrist, and are used to assess bone health for osteoporosis and fracture risk.
3
Testing bone density is the only way to know for sure if you have osteoporosis and the most widely used scan is DEXA.
4
The test is done on bones that are most likely to break due to osteoporosis, including the lower spine bones, the femur neck and bones in the forearm.

Testing your bone density -- how strong your bones are -- is the only way to know for sure if you have osteoporosis. The most widely used is a scan called dual energy X-ray absorptiometry (DXA or DEXA). The test determines bone health and your risk of fracture due to osteoporosis
