2025年2月13日 · Bone mineral density testing can: Identify and diagnose osteoporosis. Measure the risk of fractures (broken bones). Monitor the effectiveness of osteoporosis treatment. What tests are used to measure bone mineral density? The most common bone mineral density test is a central dual energy x-ray absorptiometry (DXA or DEXA).

Bone mineral density tests measure the solidness and mass (bone density) in the lumbar spine, hip, and/or wrist, which are the most common sites of fractures due to osteoporosis. Other tests measure bone density in the heel or hand.

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 ...

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).

2009年5月1日 · Bone density is between 1 and 2.5 SD below the young adult mean (-1 to -2.5 SD). Bone density is 2.5 SD or more below the young adult mean (-2.5 SD or lower). Bone density is more than 2.5 SD below...

BMD Test results are reported as T-scores and Z-scores: T-score: Normal: -1.0 and above; Osteopenia (low bone density): Between -1.0 and -2.5; Osteoporosis: -2.5 and below; Z-score: Compares bone density to others of the same age, gender, and size. A score below -2.0 may indicate abnormal bone loss. Normal Range

2024年12月6日 · Bone Mineral Density (BMD) testing is a helpful for determining your risk for osteoporosis and fractures. Learn how to interpret BMD test results with the given studies and definitions.

2019年12月17日 · Knowing your Z-score can help you compare your own bone mineral density (BMD) to those of a healthy person of the same age and body size as you, and help predict your risk of bone fractures or osteoporosis. Keep reading to learn about low and high BMD Z-scores, as well as ways to increase it. What is a Z-Score?

骨質密度 (BMD) 檢查就像骨骼的體檢，能快速評估骨骼的健康狀況，檢查結果會與健康年輕人的平均骨質密度進行比較，從而計算出一個分數，稱為 T 評分。 如果 T 評分低於0，會用負數表示；若負數的值愈大，表示骨質密度愈低，將來發生骨折的風險也愈高。 骨質疏鬆症與維他命D有關？ 骨質疏鬆你有份？ Copyright © CUHK Medical Centre Limited. All rights reserved.

2019年4月18日 · Bone mineral densitometry is a test done to measure a person's bone mineral density (BMD). The measurements are used for the diagnosis of osteoporosis , estimation of the fracture risk and assessment of response to treatment. There are three ways of checking your BMD, but the most commonly used method is DEXA.
