Two‐dimensional single‐shot diffusion‐weighted stimulated EPI with reduced FOV for ultrahigh‐b radial diffusion‐weighted imaging of spinal cord

High‐resolution diffusion‐weighted imaging (DWI) of the spinal cord (SC) is problematic because of the small cross‐section of the SC and the large field inhomogeneity. Obtaining the ultrahigh‐b DWI poses a further challenge. The purpose of the study was to design and validate two‐dimensional (2D) single‐shot diffusion‐weighted stimulated echo planar imaging with reduced field of view (2D ss‐DWSTEPI‐rFOV) for ultrahigh‐b radial DWI (UHB‐rDWI) of the SC.
