3D Dixon TSE scans essentially provide the same information as several conventional 2D TSE scans in different orientation, without and with fat suppression. However, their scan time is usually still too long for clinical practice. In this work, the basic feasibility of accelerating a 3D Dixon TSE scan with PD weighting by a combination of compressed sensing and parallel imaging was investigated in knee imaging. Results obtained in half the scan time compared to the use of parallel imaging alone are presented, which indicate that 3D Dixon TSE scans may become as fast as current, conventional 3D TSE scans with fat suppression.
