Herein, we adopted diffusion-weighted imaging (DWI) with a high fat suppression effect and high signal-to-noise ratio (SNR) in the cervical region, where magnetic field inhomogeneity may occur, using integrated slice-by-slice shimming (iShim), which improves static magnetic field (B0) shimming accuracy. We examined spinal cord SNR and standard deviation in healthy volunteers and performed cervical DWI with the conventional B0 shimming method and iShim, respectively. Furthermore, to verify whether short TI inversion recovery (STIR) or water excitation (WE) was appropriate as a fat suppression method, we used DWI with a high SNR at the cervical region by combining iShim with WE.
