2025年2月13日 · 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.

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.

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.

BMD（Bone Mineral Density，骨質密度）和DEXA（Dual-Energy X-ray Absorptiometry，雙能量X光吸收法）是兩種常見的骨質密度檢測技術，但它們之間存在一些差異。 首先，DEXA是一種特定的檢測技術，使用兩種不同能量的X光來測量骨骼的密度。

2023年3月15日 · Z-score（Z-评分）用于比较患者与正常同龄人之间骨密度（BMD）的标准差，其计算公式为：（骨密度测定值－同种族同性别同龄人骨密度均值）/同种族同性别同龄人骨密度标准差。

2012年11月23日 · Dual-energy x-ray absorptiometry (DEXA) is the technique of choice in the assessment of bone mineral density (BMD) , the average concentration of mineral in a defined section of bone . DEXA is a quick method that is accurate (exact measurement of BMD), precise (reproducible), and flexible (different regions can be scanned) and is performed with ...

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?

2025年1月30日 · DEXA (dual x-ray absorptiometry) scans measure bone density (thickness and strength of bones) by passing a high- and low-energy x-ray beam (a form of ionizing radiation) through the body, usually in the hip and the spine. DEXA scans are often used to diagnose specific conditions, such as bone thinning.

Bone densitometry, (also known as DEXA), is a special type of x-ray that measures bone mineral density (BMD). It gives doctors helpful information about bone strength or fragility, and the risk of fractures or broken bones.

Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD). An x-ray exam helps doctors diagnose and treat medical conditions.
