AbstractThe interest in non-invasive methods of body composition assessment is on the rise in health care, especially because of its association with clinical outcomes. Technology has revolutionized our understanding of body composition abnormalities, clinical prognostication, and disease follow-up, but translation to bedside is limited, especially in terms of cost effectiveness. Computed tomography gained increased attention in cancer and sarcopenia studies, for instance. Other methods also have interesting features and applications, including bedside ultrasonography, bioelectrical impedance analysis, and dual x-ray absorptiometry. Compelling evidence indicates these methods can be used to accurately and precisely measure skeletal muscle mass, adipose tissue, and edema; diagnose malnutrition-related diseases; and aid in determining prognoses. To apply this technology properly, it is important to understand the advantages and disadvantages of each technique in specific situations of interest. This review introduces concepts and reference studies published in the scientific literature about these techniques and describes important limitations and considerations necessary to incorporate these methods into clinical practice.Copyright © 2018 Elsevier Inc.
