This article reviews the dual-energy x-ray absorptiometry (DXA) technique, its interpretation, and clinical applications with emphasis on the considerations unique to pediatrics. Specifically, the use of DXA in children requires the radiologist to be a "clinical pathologist," monitoring the technical aspects of the DXA acquisition, a "statistician" knowledgeable in the concepts of Z-scores and least significant changes, and a "bone specialist," aware of the DXA findings in a large number of clinical diseases, providing the referring clinician with a meaningful context for the numeric result obtained with DXA.
本文回顾了双能X线吸收测定法（DXA）技术、其解读方法及临床应用，重点关注儿科特有的注意事项。具体而言，在儿童中使用DXA要求放射科医生成为一名“临床病理学家”，监测DXA采集的技术方面；成为一名熟悉Z评分和最小有意义变化概念的“统计学家”；以及成为一名了解大量临床疾病中DXA检查结果的“骨专科医生”，为转诊的临床医生提供与DXA获得的数值结果相关的有意义背景信息。
