目前,英国有 3 家拥有双能 X 射线吸收仪 (DXA) 机器的制造商:Hologic、Lunar 和 Norland。它们具有相似的规格,但产生两种能量束的方法不同、校准技术不同以及分析扫描以选择感兴趣区域 (ROI) 的方法不同。评估三个制造商的结果的可比性似乎很重要。这项研究使用模型来比较脊柱和全身扫描。
Currently there are three manufacturers with dual-energy X-ray absorpiometer (DXA) machines operating in Britain: Hologic, Lunar and Norland. They have similar specifications, but different methods of deriving the two energy beams, different techniques of calibration and different ways of analyzing the scans to select regions of interest (ROI). It seemed important to assess the comparability of results from the three manufacturers. This study uses models to make comparisons of spine and whole body scans.
