The analysis of body composition is a fundamental part of a nutritional status assessment, and the use of diagnostic imaging methods has been increasingly required for an adequate characterization of the lean body mass and fat mass. Body composition measurements are useful in evaluating the effectiveness of nutritional interventions and monitoring changes associated with aging and chronic diseases. Whole-body densitometry using dual-energy X-ray absorptiometry (DEXA) is one of the most widely used methods in clinical practice, allowing highly accurate assessment of the bone mineral content, lean body mass, and fat mass. Although a DEXA examination provides a lot of information, there is still no universal standardization of the parameters to be included in radiology reports. The aim of this study was to review the most relevant information for assessing body composition by whole-body densitometry.
身体成分分析是营养状况评估的一个基本组成部分，为了充分描述瘦体重和脂肪量，对诊断成像方法的需求日益增加。身体成分测量有助于评估营养干预措施的有效性，并监测与衰老和慢性疾病相关的变化。使用双能X线吸收法（DEXA）进行全身密度测定是临床实践中使用最广泛的方法之一，它能够高度准确地评估骨矿物质含量、瘦体重和脂肪量。尽管DEXA检查能提供大量信息，但放射学报告中应包含的参数仍未实现普遍标准化。本研究的目的是回顾通过全身密度测定评估身体成分的最相关信息。
