DXA Scan (Bone Density Test): What Is It & How It's Done - Cleveland Clinic
2024年5月28日 · A DXA scan (bone density test) is a quick, painless way to check your bone health. It’s similar to a regular X-ray, but measures the strength and mineral content of your bones instead of just taking pictures of them. Providers use DXA scans to screen you for osteoporosis, osteopenia and other conditions that can silently weaken your bones.
What's your t-score? Bone density scans for osteoporosis
2023年3月22日 · The DEXA scan or ultrasound will give you a number called a T-score, which represents how close you are to average peak bone density. The World Health Organization has established the following classification system for bone density:
Bone Density Test, Osteoporosis Screening & T-score …
What Is a Bone Density Test? DXA is a non-invasive test to measure bone density. A bone density test is a measurement of how much mineral, such as calcium, you have in your bones. The most common and most versatile test is with dual-energy X-ray absorptiometry (DXA).
Bone Mineral Density Tests: What the Numbers Mean | NIAMS
The most common bone mineral density test is a central dual energy x-ray absorptiometry (DXA or DEXA). DXA uses radiation to measure how much calcium and other minerals are in a specific area of your bone. Because the weak bones that tend to break most often are the hip and spine, DXA usually measures bone mineral density in these bones.
