Abdominal fat is associated with an increased risk for various diseases and can be quantified with MRI. Manual segmentation of subcutaneous (SAT) and visceral adipose tissue (VAT) is time consuming while automatic analyses are prone to errors. Therefore, an automatic technique with manual correction option was developed. Good agreement was observed between two readers for manual VAT and SAT quantification in 10 obese patients. Automatic volumes were 178% (VAT, p<0.001) and 13% (SAT, p=0.397) higher than the manually derived. These preliminary results suggest that the combined approach holds great promise for a fast (6 min) and sufficiently accurate fat quantification.
