A DEXA scan, or dual-energy X-ray absorptiometry, is a type of medical imaging test that measures bone density (strength) . It is considered the most useful, easy, and inexpensive test for helping to diagnose osteoporosis. The test uses very low levels of x-rays to measure how dense your bones are. DEXA scan results can provide helpful details about your risk for osteoporosis (bone loss) and fractures (bone breaks) . The scan is quick and painless, and there are no needles or injections involved. During the scan, a large scanning arm will be passed over your body to measure bone density in the center of the skeleton. As the scanning arm is moved slowly over your body, a narrow beam of low-dose X-rays will be passed through the part of your body being examined. The scan usually takes 10 to 20 minutes.

In addition to measuring bone density, there is also a type of DEXA scan called DXA body composition analysis that can provide an in-depth analysis of your fat tissue, lean mass, and bone density. This scan requires very minimal preparation and is quick and pain-free. It is beneficial to do this scan every 3-6 months for body composition and every year if you are looking to modify something specific such as bone density.

Overall, a DEXA scan is a useful tool for assessing bone density and the risk of osteoporosis and fractures. It is a quick and painless procedure that involves lying on your back on an X-ray table so an area of your body can be scanned.
