Adipose tissue distribution as assessed by magnetic resonance imaging and total body fat by magnetic resonance imaging, underwater weighing, and body-water dilution in healthy women

摘要: A method for estimating total body fat (TBF) and the amount distribution of adipose tissue in humans by using magnetic resonance imaging (MRI) is described. Thirty transaxial images subjects were taken a nuclear imager (0.02 T). Adipose volume was calculated from area each image distances between images. The CV when 1.5%. TBF healthy Swedish women estimated MRI (n = 25), underwater weighing (UWW) 20), body-water dilution (BWD) 23). When assessed BWD, contained 1.4 +/- 2.9% less 4.7 4.0% more TBF, respectively, than UWW. On average, 74.2% situated subcutaneously. Subcutaneous fat:fat-free weight nonsubcutaneous both significantly correlated with percent but stored excess subcutaneously rather nonsubcutaneously.
