What is a DEXA scan?
A dual-energy X-ray absorptiometry test (DEXA) scan is an imaging test used to determine bone density; specifically, it measures the calcium and mineral composition of bones. DEXA scans are usually performed to diagnose osteoporosis and bone loss that occurs with aging.
Bones lose density as we age, becoming more brittle and breakable. Osteoporosis is the medical term for this process. Many people do not realize that they are managing osteoporosis until they are injured; usually, a broken bone caused by a fall. Osteoporosis is a common condition among aging individuals but is especially prevalent among post-menopausal women.
