Dual Energy X-ray Absorptiometry
Dual energy X-ray absorptiometry (DEXA) is a test that measures the density (or thickness) of your bones.
The DEXA scan is an x-ray scan that uses a small amount of radiation to take pictures of different bones. These pictures are used to measure the density of the bones at the spine, hip, forearm. It can also take pictures of other bones such as a finger or the heel bone. Measurements of the spine and hip are called central DXA. Those done on the arms or legs are called peripheral DXA. In some cases, your doctor may order a whole body scan.
This test will help your doctor assess the density of your bones. It will help determine if you have osteoporosis, a bone-thinning disease. This information may be used to predict your risk of bone fractures.
