Bone densitometry, also called dual-energy x-ray absorptiometry or DEXA, uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower spine and hips) to measure bone loss. It is commonly used to diagnose osteoporosis and to assess an individual’s risk for developing fractures. DEXA is simple, quick and noninvasive. It’s also the most accurate method for diagnosing osteoporosis.
Wear comfortable clothing. Metal objects like belt buckles, rivets, snaps, zippers, and buttons over the mid-abdomen or hip areas interfere with the scan and you will need to remove them.
