An acquisition method is presented which provides full volume coverage of the entire abdomen in a total measurement time of 70 seconds with only one breath-hold required. The method uses GRE-based transverse 2D-volume acquisition with continuous table motion combined with parallel imaging techniques. The upper 18 cm of the abdomen are recorded during a 20 seconds breath-hold phase which provides an image quality that is comparable to standard multiple-breath-hold approaches with stationary table. An acquisition regime for minimized FOV-usage increases the data homogeneity along the z-direction and makes the technique suitable for being used on short bore magnets.
