Quantitative abdominal fat estimation using MRI
2008
Pattern Recognition (ICPR), Proceedings of the International Conference on
Preserved Fulltext
This paper introduces a new method for automatic quantification of subcutaneous, visceral and nonvisceral internal fat from MR-images acquired using the two point Dixon technique in the abdominal region ...
This is followed by an integration of the corrected fat images within the different fat compartments that avoids the partial volume effects associated with traditional fat segmentation methods. ...
In order to study such effects, we have developed a novel method for quantitatively measuring the abdominal fat composition from MR images. ...
