The two-point Dixon (2PD) technique is capable of achieving unambiguous water-fat separation even in the presence of magnetic field inhomogeneities. However, the need to acquire two sets of images prolongs scan time, giving rise to the primary drawback of the 2PD technique. Bunched Phase Encoding (BPE) has recently been proposed as a new fast data acquisition method in MRI. In BPE, the total number of TR cycles can be reduced. In this study, it is shown that the total acquisition time of the 2PD technique can be reduced to that of a single acquisition by capitalizing on the BPE technique.
