Helical Computerized Tomography Can Measure Subcutaneous, Visceral and Total Fat Areas?

Abstract

Background: Abdominal obesity or android obesity, that is, the increase in adipose tissue in the abdominal region, is considered a risk factor for several morbidities. Different ways of quantifying it have been proposed, one method is the measurement of the abdominal fat area by computed tomography. Aim: To establish correspondence between the groups defined by degree of obesity in relation to the total, subcutaneous and visceral fat area. Methods: Cross-sectional observational study carried out through the analysis of tomographic examinations. Horos v3.3.5 medical image visualization software was used, with abdominal tomography in a single cut including the L4 vertebral body and the umbilical scar, to obtain the areas of total, visceral and subcutaneous fat. Results: Of the 40 patients, 10 had grade II obesity, 23 grade III and 7 superobese. The amount of total fat showed an increase in relation to the degree of obesity. Visceral fat did not show significant differences between the degrees of obesity, but the data showed a lower average in the group of obesity grade II. The area of subcutaneous fat, as well as total fat, showed an increase in its measurements, according to the progression of the patients’ BMI, but there was no statistical significance in this difference between the groups of grade II and super-obese individuals. Conclusion: The area of total and subcutaneous fat showed an increase in its measurements according to the progression of the BMI groups, which did not happen with visceral fat.

“…Evidências indicaram que a proporção de tecido adiposo abdominal, tecido adiposo visceral em particular, é uma correlata chave e talvez um fator principal de problemas de saúde relacionados à obesidade, porque tem sido associado com um risco aumentado para comorbidades como o diabetes mellitus tipo 2, acidente vascular cerebral, apneia do sono, hipertensão, dislipidemia e alguns tipos de câncer (Trinks, et al, 2019;Freitas, et al, 2020;Wendler, et al, 2022;Sasaki, et al, 2021).…”

“…Segundo, se dibuja el contorno externo de los músculos del abdomen y se cuantifica la grasa subcutánea con la herramienta "2D Growing region", algoritmo threshold, con valores UH entre -200 y 0. Tercero, se crea una nueva serie del ROI dibujado y se cuantifica la grasa visceral con la herramienta "2D Growing region" de manera similar a la previamente descrita (61).…”
