双能X线骨密度仪（DXA）是测量骨矿物质密度（BMD）、诊断骨质疏松症和监测BMD随时间变化的金标准。DXA数据也用于确定骨折风险。DXA扫描的程序步骤可分为扫描采集、分析、解释和报告。仔细注意与这些程序步骤有关的质量控制理论上应该有利于患者管理。不注意程序步骤和每个步骤可能发生的错误可能会提供信息，从而导致不适当的临床决策，产生不必要的医疗费用，并最终对患者造成可避免的伤害。本文综述了DXA扫描中影响机器、患者和技术人员相关的真实度和精度的错误，并回顾了记录临床和研究环境中DXA质量问题的文章。了解DXA错误对于DXA质量至关重要; DXA技术人员和口译员的认证等计划有助于确保高质量的骨密度测定。由于DXA错误是常见的，支付性能要求DXA技术人员和口译员进行认证，并遵循质量指标的指示。(C)2017 Elsevier Inc版权所有。
Dual-energy X-ray absorptiometry (DXA) is the gold standard for measuring bone mineral density (BMD), making the diagnosis of osteoporosis, and for monitoring changes in BMD over time. DXA data are also used in the determination of fracture risk. Procedural steps in DXA scanning can be broken down into scan acquisition, analysis, interpretation, and reporting. Careful attention to quality control pertaining to these procedural steps should theoretically be beneficial in patient management Inattention to procedural steps and errors that may occur at each step has the possibility of providing information that would inform inappropriate clinical decisions, generating unnecessary healthcare expenses and ultimately causing avoidable harm to patients. This article reviews errors in DXA scanning that affect trueness and precision related to the machine, the patient, and the technologist and reviews articles which document problems with DXA quality in clinical and research settings. An understanding of DXA errors is critical for DXA quality; programs such as certification of DXA technologists and interpreters help in assuring quality bone densitometry. As DXA errors are common, pay for performance requiring DXA technologists and interpreters to be certified and follow quality indicators is indicated. (C) 2017 Elsevier Inc All rights reserved.
