A DEXA scan is a high-precision type of X-ray that measures your bone mineral density and bone loss. If your bone density is lower than normal for your age, it indicates a risk for osteoporosis and bone fractures. DEXA stands for dual energy X-ray absorptiometry. This technique was introduced for commercial use in 1987.
DEXA stands for 'dual-energy X-ray absorptiometry'. DEXA (also sometimes known as DXA) is a test that measures the density of bones. Density means how much of something there is in a certain amount of space. The denser the tissue, the less X-rays pass through. Air and water are less dense than solid things such as bone.
DEXA bone density tests are outpatient procedures. You may be able to wear your regular clothes during the test. Or you may be asked to change into a hospital gown. There are no needles or injections in this test. Getting a DEXA test is similar to having a standard X-ray.
While a regular X-ray can show changes in bone density ( osteopenia) after bone loss of about 40%, a DEXA scan can detect changes as small as 1%, making it more sensitive and accurate. The DEXA is sometimes referred to as a central DEXA scan, bone densitometry scan, or a DXA scan.
