“…4,[15][16][17] Ultrasound scan is a noninvasive method which can be used to image body fat without radiation exposure. To date, it has been used to measure subcutaneous [18][19][20] and preperitoneal fat 21,22 as well as visceral thickness (distance between anterior abdominal wall and anterior surface of aorta). 7,21,23 The abdominal wall fat index expressed as a ratio of preperitoneal to subcutaneous fat thickness has been developed to assess the relationships between adipose tissue and obesity-related complications.…”

Objective: Mesenteric fat is drained by the portal circulation and has been suggested to be a key component in obesity-related health risk, notably the metabolic syndrome. There are increasing epidemiological and experimental data showing that fatty liver is another component of this multifaceted syndrome. Given their intimate anatomical and physiological relationships, we hypothesized that mesenteric fat thickness may be independently associated with the risk of fatty liver. To test this hypothesis, we examined the predictive role of various fat deposits including mesenteric fat thickness, and various metabolic variables on the risk of fatty liver. Subjects and methods: A total of 291 Chinese subjects (134 men and 157 women with a mean BMI of 23.7 kg/m 2 , range: 16.5-33.4 kg/m 2 ) underwent ultrasound examination for measurement of mesenteric, subcutaneous and preperitoneal fat thickness, and for diagnosis of fatty liver. Body mass index, waist circumference, and waist-hip ratio were recorded. Blood pressure was measured. Fasting plasma glucose, insulin resistance, high-density lipoprotein cholesterol (HDL-C), triglycerides, low-density lipoprotein cholesterol (LDL-C), liver enzymes were determined by common methods. Results: The subjects with fatty liver had greater abdominal fat thickness and higher anthropometric indexes than those without fatty liver. The subjects with fatty liver also showed higher blood pressure, worse lipid and glycaemic profile compared with those without fatty liver. Using multiple logistic regression analysis, mesenteric fat thickness was a risk factor of fatty liver, independent of body mass index, age, sex, insulin resistance, fasting plasma glucose, lipid and blood pressure. The odds ratio was 1.5 (95% confidence interval: 1.27-1.77) for every 1 mm increase in the mesenteric fat thickness. Measurement of preperitoneal and subcutaneous fat deposits did not show significant associations with fatty liver. Conclusion: Mesenteric fat thickness measured on ultrasound is an independent determinant of fatty liver.

“…To date, it has only been used to measure subcutaneous fat [9][10][11] and preperitoneal fat thickness. 12,13 However, these fat deposits are not usually regarded as visceral fat drained by the portal system. 13 By contrast, mesenteric fat can be easily recognized by ultrasound scan, especially in obese subjects with thickened mesenteries.…”

OBJECTIVE: Visceral fat, notably mesenteric fat, which is drained by the portal circulation, plays a critical role in the pathogenesis of metabolic syndrome through increased production of free fatty acids, cytokines and vasoactive peptides. We hypothesize that mesenteric fat thickness as measured by ultrasound scan could explain most of the obesity-related health risk. We explored the relationships between cardiovascular risk factors and abdominal fat as determined by sonographic measurements of thickness of mesenteric, preperitoneal and subcutaneous fat deposits, total abdominal and visceral fat measurement by magnetic resonance imaging (MRI) and anthropometric indexes. DESIGN: A cross-sectional study. SUBJECTS: Subjects included 18 healthy men and 19 women (age: 27-61 y, BMI: 19-33.4 kg/m 2 ). MEASUREMENTS:The maximum thickness of mesenteric, preperitoneal and subcutaneous fat was measured by abdominal ultrasound examination. MRI examinations of whole abdomen and pelvis were performed and the amount of total abdominal and visceral fat was quantified. The body mass index, waist circumference and waist-hip ratio were recorded. Cardiovascular risk factors were assessed by physical examination and blood taking. RESULTS: Men had more adverse cardiovascular risk profile, higher visceral fat volume and thicker mesenteric fat deposits than women. Among all the investigated obesity indexes, the mesenteric fat thickness showed the highest correlations with total cholesterol, LDL-C, triglycerides, fasting plasma glucose, HbA 1c and systolic blood pressure in men, and with triglycerides and HbA 1c in women. On stepwise multiple regression analysis with different obesity indexes as independent variables, 30-65% of the variances of triglycerides, total cholesterol, LDL-C and HbA 1c in men, and triglycerides in women were explained by the mesenteric fat thickness. CONCLUSION: Compared with sonographic measurement of subcutaneous and preperitoneal fat thickness, MRI measurement of total abdominal and visceral fat and anthropometric indexes, sonographic measurement of mesenteric fat thickness showed better associations with some of the cardiovascular risk factors. It may potentially be a useful tool to evaluate regional distribution of obesity in the assessment of cardiovascular risk.

“…Ultrasonography is a reliable and convenient method for quantifying the amount of abdominal fat, and a variety of ultrasonographic values have been reported as useful [4][5][6][7][8] . However, few previous studies have considered the relationship between WC and abdominal fat accumulation measured by ultrasonography.…”

Abstract. [Purpose] We examined the relationship between waist circumference (WC) and accumulated abdominal fat measured by ultrasonography in healthy adult men.[Subjects] The study subjects were 20 healthy men. [Methods] The measured items were maximum preperitoneal fat thickness (PFT), minimum subcutaneous fat thickness (SFT), and WC. PFT and SFT were measured by ultrasonography. Associations between PFT, SFT, and WC were evaluated using Pearson's correlation coefficients. Study subjects were divided into two groups: those with WC < 85 cm and those with WC ≥ 85 cm. This cut-off was based on Japanese reference values. These groups were then compared for differences in PFT using the independent-sample t test. [Results] There was a moderately significant correlation between PFT and WC (r = 0.56, p < 0.05). In contrast, there was no significant correlation between SFT and WC (r = 0.15; p = 0.52). Furthermore, the group with WC ≥ 85 cm had higher PFT values than the group with WC< 85 cm.[Conclusion] Our findings support the hypothesis that WC is a simple anthropometric index of intraabdominal fat accumulation in healthy adult men.
