Figure 2

Example of two-point CSI technique. In-phase (IP) and out-of-phase (OP) images from two subjects are shown. In the OP images, a dark line is present at all fat and lean tissue interfaces. This is caused by signal cancellation between fat and water species within the voxels. All IP and OP images are displayed on the same grayscale. In (a), signal intensities within the liver between the two images are similar, indicating very little presence of hepatic fat. However in (b), the liver signal intensity is markedly lower in the OP image (dashed region), indicative of fat presence. This is visualized in the zoomed difference images. The liver in (a) exhibits residual signal whereas that in (b) shows appreciable signal. As corroborated by MRS, the hepatic fat fractions were 3.4% and 21.2%, respectively
