A DEXA scan, also known as dual-energy X-ray absorptiometry, is a medical imaging test used to measure bone density. It’s the most accurate method for diagnosing osteoporosis, a condition that weakens bones and increases the risk of fractures. The scan uses low-level X-rays to assess the mineral content in specific areas, such as the hip, spine, and wrist. A DEXA scan is quick, painless, and non-invasive, typically taking 10 to 20 minutes. It is commonly recommended for postmenopausal women, older adults, and individuals with a family history of bone health issues to monitor bone health and prevent complications.
