Bioimage as a method of evaluation of subcutaneous and visceral fat: from the state of art to practical applications
Abstract
Introduction: over the last three decades, a significant increase in the prevalence of obesity has been observed and verified worldwide. Objective: to study the importance of imaging methods for the evaluation of obesity. Materials and methods: a bibliographic survey was carried out, in which international journals were consulted, available in the Web database, Pubmed. The descriptors used for the search of the articles were: ((resonance AND tomography) AND subcutaneous adipose tissue; ((resonance AND tomography) AND abdominal fat.) Original articles published between 2010 and 2015 were selected, in addition to the incorporation of classic papers previously published , and that the bioimaging techniques used in the present study were based on the results obtained by the authors, RM and USG are more advantageous to determine the abdominal fat in comparison to the others verified, and the anthropometric measurements, since they allow to identify the volumes of subcutaneous and visceral adipose tissue separately. A precise characterization of the volumes of visceral abdominal adipose tissue and subcutaneous is important to evaluate the risk of developing metabolic diseases related to obesity, since visceral abdominal adipose tissue is more associated with metabolic dysfunctions than subcutaneous adipose tissue. Conclusion: imaging techniques for the diagnosis of obesity generally allow the direct acquisition of adipose tissue volumes in specific compartments, but their high costs are obstacles to regular use as screening methods.
