DEXA bone densitometry is a quick, painless procedure for measuring bone loss due to osteoporosis. To detect osteoporosis accurately, doctors use an enhanced form of x-ray technology called Dual-Energy X-ray Absorptiometry. DEXA bone densitometry is the established standard for measuring bone mineral density. Most often the test focuses on the lower spine and hips. When should women have a bone densitometry test? Around menopause, estrogen production slows down, making you more prone to loss of bone density. You should have a test at that time because it is important to have a baseline density so we can compare the results with future measurements to determine your rate of bone decay, if any. How do I prepare for the test? There is no preparation required for this test. Is it safe? Using less radiation than a standard chest x-ray, DEXA is extremely safe and effective. What happens during the procedure? DEXA is one of the simplest imaging procedures available. Generally you can remain dressed if you avoid clothing with metal, such as zippers. You simply lie on a padded table while the imager passes over you. How long does the procedure take? DEXA takes about 15 to 20 minutes. There is no preparation required, nor any medication or injections involved. Why is this test important? Loss of bone density (osteoporosis) is a very real concern of post-menopausal women. The lower your bone density, the higher your risk for a painful, debilitating fracture. Regular testing lets your physician keep track of your bone density and work with you to lower your risks through preventive therapies.
