Abstract
Computed tomography (CT) is a direct and reference technique for body composition analysis with interesting possibilities in clinical nutrition. Segmentation is the automatic or semi-automatic software-based process by which different metabolic tissues of interest (muscle tissue, subcutaneous adipose tissue, visceral adipose tissue and intermuscular adipose tissue) that are part of the current diagnoses of malnutrition, sarcopenia and sarcopenic obesity are delimited, separated and quantified. The Alberta protocol is the most common segmentation guide, being applicable in most software. In this paper, we review the main characteristics of the most common open-source segmentation software, their degree of agreement, and some precautions and limitations of this process.
期刊介绍：
The journal Nutrición Hospitalaria was born following the SENPE Bulletin (1981-1983) and the SENPE journal (1984-1985). It is the official organ of expression of the Spanish Society of Clinical Nutrition and Metabolism. Throughout its 36 years of existence has been adapting to the rhythms and demands set by the scientific community and the trends of the editorial processes, being its most recent milestone the achievement of Impact Factor (JCR) in 2009. Its content covers the fields of the sciences of nutrition, with special emphasis on nutritional support.
