DXA Scan (Bone Density Test): What Is It & How It's Done
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.
Bone density test - Mayo Clinic
A bone density test determines if you have osteoporosis — a disorder characterized by bones that are more fragile and more likely to break. The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone.
Bone Density Test: Uses, Side Effects, Procedure, and Results
2022年11月2日 · A bone density test can help diagnose osteopenia and osteoporosis, which decrease bone density and strength, but does not show arthritis. It is a painless procedure that takes place at a hospital, medical clinic, or outpatient imaging center.

2024年9月2日 · Bone density tests (also called bone mineral density tests or BMD tests) check how strong your bones are by measuring a small part of one or a few of them. The results can help...
DEXA Scan (Bone Density Test): Preparation and What to Expect
2024年8月6日 · What is a DEXA scan? A DEXA scan is a high-precision type of X-ray that measures your bone mineral density and bone loss. If your bone density is lower than normal for your age, it indicates a...
Bone Mineral Density Tests: What the Numbers Mean | NIAMS
A bone mineral density (BMD) test measures calcium and other minerals in bone. Bones containing more minerals are denser, so they tend to be stronger and less likely to break. Bones can become less dense as we age or if we develop certain medical conditions.
Bone Mineral Density Test: Purpose, Procedure, and Results
2024年9月2日 · A bone mineral density test examines segments of your bone through X-rays to detect osteoporosis. The test is quick and painless, and it gives you a snapshot of how strong...
Bone Density Test, Osteoporosis Screening & T-score Interpretation
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 Densitometry - Johns Hopkins Medicine
What is a bone density test? A bone density test is used to measure bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.
Bone Density: What It Is and How to Keep What You’ve Got
Bone density testing is done to measure the mineral density of the bones. You should be scanned at four sites of interest: four lumbar vertebrae, in the lower spine; the femur, or hip bone; the femoral neck, which is the skinny part of the hip bone; and the wrist.
