A method for calculation of total lean and adipose tissue volume based on intensity corrected whole body water-fat separated MRI is presented. The method was validated comparing data acquired from healthy volunteers scanned at different field strengths, resolutions and vendors. The whole body adipose tissue volume was also compared to air displacement plethysmography. Both adipose and lean tissue measurements showed excellent reproducibility between different MRI measurements as well as compared to air displacement plethysmography.
