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.
