Single-shot echo-planar imaging is not widely used for DWI of the cervical spine, because of the magnetic ﬁeld inhomogeneities around the spine and the increased motion in that area due to breathing and swallowing. To solve this problem, in this study, we combined the reduced FOV and 2D phase cycling Multi-shot methods together to improve the DW image quality. Results show that image quality is best in this combined new acquisition except the slightly low SNR which can be compensated by extending the scan time.
