Twenty-five million Americans have osteoporosis (the most common bone disease). Fifty thousand people die each year because of it. Yet most of us know little about protecting ourselves from this disease.
DEXA is an acronym for dual-energy X-ray absorptiometry. DEXA uses low-energy X-rays to measure the density of bones. When measuring bone density, the DEXA scan is usually performed on the lower spine, hip and sometimes the forearm. Different from a standard X-ray, a DEXA scan provides detailed information specific to the density of the bones and compares the results to standards set by the World Health Organization. The resulting scan is reviewed by a radiologist, who then generates a report for the ordering provider.
