Bone Mineral Density Tests: What the Numbers Mean
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.
DXA Scan (Bone Density Test): What Is It & How It's Done - Cleveland Clinic
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 Chart | T Score Chart - How to Understand
2020年6月23日 · DEXA bone scan results scores are measured as T-scores, which is a comparison of a person’s bone density with that of a healthy 30-year-old adult. The lower bone density test results, the lower your total bone density, indicating osteopenia or osteoporosis.
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 Mineral Density (BMD) Test - Cleveland Clinic
These BMD tests are called dual-energy X-ray absorptiometry (DEXA) tests. DEXA scans use small, safe doses of radiation to look at your bones. You may also have a vertebral fracture assessment (VFA) along with a DEXA test.

2022年8月10日 · What is a bone density test? Who should have a DEXA bone density test? What happens during a DEXA scan? What do my DEXA scan results mean? Does arthritis show up on a bone density test? At what age should you stop getting tested?
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.
Dual-Energy X-Ray Absorptiometry - StatPearls - NCBI Bookshelf
2024年5月20日 · DEXA imaging is the best clinical tool for assessing BMD in the evaluation of osteoporosis, and its validity is evident, given its ubiquity among international guidelines. Evaluation of primary and secondary osteoporosis cannot be elucidated with DEXA imaging.
Bone Mineral Density Test: Purpose, Procedure, and Results - WebMD
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 they are.
Bone Density Test: Uses, Side Effects, Procedure, and Results
2022年11月2日 · Also called a bone mineral density test (BMD), a dual-energy X-ray absorptiometry test (DEXA scan), or a peripheral screening test, a bone density scan checks the hips, spine, forearms, heel, or finger for signs of decreased bone mass.
