Bone density scanning, also called dual-energy x-ray absorptiometry (DEXA) or bone densitometry, is an form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD). DXA is most often performed on the lower spine and hips. DEXA is most often used to diagnose osteoporosis, a condition that often affects women after menopause but may also be found in men. Osteoporosis involves a gradual loss of calcium, as well as structural changes, causing the bones to become thinner, more fragile and more likely to break.
In preparation for your DEXA, you will be asked to stop taking any calcium, vitamins, antacids, and any Osteoporosis/Osteopenia medications such as fosomax, actonel and boniva. You will be asked to wear loose clothing free from buttons, zippers, and metal of any kind.
