Gastric Bypass Promotes More Lipid Mobilization Than a Similar Weight Loss Induced by Low-Calorie Diet
Figure 1
Illustration of image data employed from one subject included in the study. Reconstructed fat and water images are shown in (a) and (b), respectively. The horizontal lines delineate the subvolumes analysed in (c) and (d), where the fat- [fat/(fat+water)] and water-fraction [water/(fat+water)] images calculated and used to estimate total fat and water volumes are shown, respectively. Note that the intensity variations seen in (a) and (b) are removed by the use of fraction images. The intensity in each pixel estimates its absolute fat and water contents, and by integrating the pixel contents, total volumes are obtained. Note that fat infiltration of the liver (greyish and measured to approximately 25%) can be seen in (c).
