DXA: Bone Densiometry

Osteoporosis Screening

DXA stands for dual-energy X-ray absorptiometry. This procedure is used to detect osteoporosis via a very low dose of X-ray energy. Beginning in peoples' mid-thirties, bone mineral content begins declining and in post-menopausal women it accelerates. DXA makes it possible to detect the early stages of bone density loss and enables earlier treatment. Osteoporosis is a potentially debilitating condition which can lead to more vulnerability for bone fractures, decreased mobility and independence.

What to Expect

You'll lie on a table and the exam arm will pass over your body. The only preparation needed is to avoid calcium supplements for 48 hours before your appointment. Also, if you've had any kind of barium study you'll need to wait at least 14 days between tests to avoid barium interference with the DXA exam. A DXA scan is an easy procedure for the patient and takes about 15-30 minutes. Be sure to wear comfortable, metal-free clothing.
