A method for assessment of adipose tissue distribution in children is presented. The method utilizes rapid water-fat imaging of 16 slices of the abdomen. A fully automated segmentation algorithm for assessment of visceral and subcutaneous adipose tissue volumes is described. The automatically measured results from 21 volunteer 5-year-olds are compared to those from semi-automated segmentation. Acceptable results were achieved despite the childrens young age and the relatively small adipose tissue volumes measured.
