Examples of IDEAL-fat fraction images (reconstructed using the pre-calibrated multi-peak algorithm) and the corresponding PRESS acquisition, in two patients with a) severe steatosis and b) mild steatosis. The squares shown on the fat-fraction images correspond to the location of the PRESS single voxel acquisition, and the asterisks are shown in the severe steatosis PRESS spectrum to explicitly denote the multiple peaks of fat. The agreement between IDEAL and PRESS improves when using the multi-peak reconstruction methods compared to the conventional single peak reconstruction. Note the fatty sparing near the gall bladder fossa in segment 4 (arrow).
