2025年2月13日 · 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. When too much bone is lost, osteoporosis can develop.

2024年9月2日 · What Is a Bone Mineral Density Test? A bone mineral density test, sometimes just called a bone density test, detects whether you have osteoporosis, a word that comes from Greek and literally...

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.

DXA scans are special X-rays that measure your bone density to screen you for osteoporosis and other conditions that weaken your bones. A whole-body bone scan lets providers check to see if a cancer you might have has spread (metastasized) to your bones. You might also need a whole-body bone scan to see which cancer stage you have. They can ...

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.

A BMD test can diagnose osteoporosis when your T-score is –2.5 or below, for example -2.5, -2.6,…-3.0….-3.5 and below. The lower your bone mass, the greater your risk for fracture. Osteoporosis can also be diagnosed if you have a history of a broken bone in your hip or spine without major trauma (such as a motor vehicle accident or a fall ...

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 your...

2020年8月5日 · 骨密度（即骨骼矿物质密度，bmd）是衡量骨骼强度、预测骨折风险的一个重要指标，也是中老年体检的一项常规检查项目。 骨密度的标准因人而异，我国骨密度检查标准是通过调查中国北方汉族健康人的骨密度值得出的结果作为标准。

2024年5月14日 · Bone density or bone mineral density (BMD) is the amount of bone mineral in your bones. A BMD test measures bone health and risk for breaking bones.

2015年10月20日 · 教你看懂骨密度 (BMD): 骨密度仪会根据病人测出的骨密度数据，自动算出T值和Z值数据。 T值与Z值都是相对的数值。 T值是将测出的骨密度 (BMD)数据，与同性别、健康的年轻人的骨峰值数据库作比较，得出高出（+）或低于（-）年轻人的标准差（SD），T值是诊断骨质疏松症最有意义的指标。 Z值是将测出的骨密度数据与同性别、同龄人群的骨密度数据库作比较得出的值。 Z值主要应用于对儿童的骨质疏松症诊断，对成年人可反映骨质疏松的严重程度。 世 …
