Quantitative assessment of visceral adipose tissue (VAT) is important in studies of obesity and metabolic abnormalities. The study developed and evaluated an unsupervised method for abdominal adipose tissue quantification in a large sample from the general population. The results revealed strong correlations with reference measures using dual energy X-ray and MR based methods with human intervention. We also demonstrate the relationship between body mass index (BMI) and adipose tissue compartments. As expected, BMI did not fully reflect fat accumulation in VAT. With increasing BMI, males were more likely to have higher VAT accumulation than females.
