The high-resolution images make CT scan the most accurate method to determine the bodycomposition at the tissue-organ level, specifically total and regional adipose tissue and skeletalmuscle tissue. Furthermore, this technique is able to quantify intramuscular adipose tissue, a depotof emerging importance as a prognostic marker (Prado et al. 2016; Brown et al. 2018; Xiao et al.2018). However, the large radiation exposure precludes its widespread, making it unethical to useCT imaging solely for the purpose of body composition analysis.
