Bone densitometry (DEXA)
Bone densitometry, also known as bone density scanning, uses advanced technology called DEXA (short for dual-energy X-ray absorptiometry) to safely, accurately and painlessly measure bone mineral density for the purpose of diagnosing osteoporosis. During a comprehensive examination with DEXA, the patient lies comfortably still on a padded table while the DEXA unit scans two or more areas, usually the fracture-prone hip and spine. Unlike typical X-ray machines, radiation exposure during bone densitometry is extremely low - less than the radiation exposure during a coast-to-coast airline flight. The entire process takes only minutes to complete, depending on the number of sites scanned. It involves no injections or invasive procedures; and patients remain fully clothed.
