Diffusion-prepared (dprep-TSE) TSE sequences are gaining attention for high-resolution distortion-free body DWI. However, dprep-TSE suffers from phase errors induced by both motion and eddy current effects. Motion compensation reduces motion effects, but eddy currents remain a source of phase errors. The present study investigates the performance of two alternative methods for compensating for eddy current effects in a motion-compensated dprep-TSE sequence: the use of phase cycling and the use of magnitude stabilizers.
