There are purported links between central obesity and incidence of various cancers. Visceral fat, which includes both pancreatic and liver fat, wraps around major organs, while subcutaneous fat is surface level “belly fat.” The significance of this research is due to its potential to act as another method of measuring fat, as the only methods now are imaging by a CT scan, which is a cross-sectional X-ray of a body area, or an MRI scan, which is imaging done via magnetic resonance. Cross-sectional analyses of scaled MRI images from 228 subjects of Black, Hawaiian, Japanese, Latino, and White ethnicity in the Multiethnic Cohort were performed. Statistical analysis software (SAS) 9.4 was used to perform analyses of measurements. Although there was a significant correlation with subcutaneous fat, the measurements did not prove to be neither significant nor practical predictors of overall visceral fat (r2<0.00019,p>0.1403). However, when analyses of measurements were done in both sexes, they were significant and practical predictors of overall visceral fat for women (p=0.0005, <0.05) and pancreatic fat for men (p=0.0559). When compared to waist and hip circumference measurements, the geometric measurements of the MRI images were better predictors of liver fat (r2=0.013795, r2=0.116628, respectively) and pancreatic fat (r2 = 0.113253, r2=0.132597, respectively) in males. Our findings support the use of external, geometric measurements as a means of determining overall visceral fat distribution in females and pancreatic fat, a type of visceral fat, distribution in males; it also surpass the effectiveness of waist and hip circumference in predicting liver and pancreatic fat in men.
