DXA plays a critical role in assessing skeletal health and disease, as well as, fat and muscle status in children and adolescents. Quality DXA requires training, expertise and attention to details, as in adults, but there are key differences in performing and interpretations in children. These include choice of measurement site, skills required, reference data and software, and considerations for indications and underlying disorders to facilitate correct interpretation. The International Society for Clinical Densitometry (ISCD) has been pivotal in establishing official positions and training for people who are interested in performing or interpreting such examinations, and guiding clinicians who may request such studies. However training in the performance and interpretation of scans of individuals with more complex needs falls outside the scope of this review, and consideration should be given to refer such examinations to a specialist pediatric DXA unit. Others may be scanned and reported by those with expertise in densitometry, as long as due diligence is paid to standard quality procedures, as well as knowledge of the special circumstances and training required for this field. In this invited review we outline some of these considerations, highlight key messages, and provide some appropriate references to help guide clinicians, technologists and scientists involved or interested in DXA use in children and adolescents.
DXA 在评估儿童和青少年的骨骼健康和疾病、脂肪和肌肉状况方面发挥着关键作用。与成人一样，高质量的 DXA 需要培训、专业知识和对细节的关注，但在儿童中，其执行和解释存在一些关键差异。这些差异包括测量部位的选择、所需的技能、参考数据和软件，以及对适应症和潜在疾病的考虑，以促进正确的解释。国际临床密度测定学会（ISCD）在为有兴趣进行此类检查的人员制定官方职位和培训方面以及指导可能要求进行此类研究的临床医生方面发挥了重要作用。然而，对于具有更复杂需求的个体的扫描执行和解释的培训不在本综述的范围内，应考虑将这些检查转介给专门的儿科 DXA 单位。其他人可以由具有密度测定学专业知识的人进行扫描和报告，只要对标准质量程序以及对该领域的特殊情况和培训的知识给予应有的重视。在本次特邀评论中，我们概述了其中的一些注意事项，强调了关键信息，并提供了一些适当的参考文献，以帮助指导参与或有兴趣在儿童和青少年中使用 DXA 的临床医生、技术人员和科学家。
