A Bone DEXA scan (Dual-Energy X-ray Absorptiometry) is a specialized imaging test used to measure bone density. It helps doctors assess your risk of osteoporosis, fractures, and bone loss. Using low-level X-rays, DEXA provides accurate information about your bone health in areas like the spine, hip, or wrist. The test is quick, painless, and highly reliable in detecting early bone weakening.
