Calculated in-phase and opposed-phase images can be produced from dual-echo Dixon imaging with flexible echo times. Potentially, this sequence could replace the standard in-phase and opposed-phase multi-slice FFE scan in a liver exam, shortening exam times. For adequate resolution, however, the 3D dual-echo Dixon scan must be acquired with partial Fourier during a breathhold. Partial Fourier acquisitions complicate Dixon reconstruction as phase information is compromised. This study evaluates a new partial Fourier reconstruction method that is compatible with analytical Dixon water-fat separation.
