DWI plays a critical role in many neurological applications but its adoption in spinal imaging has been significantly hindered by geometric distortions in EPI, which is widely used in the clinic. TSE-based DWI methods, including PROPELLER and turboPROP, are free from distortion artifacts but may not be optimal for spinal imaging. In this work we present a single-shot GRASE technique with whole-mode acquisition and reduced FOV imaging to provide rapid and robust high-resolution spinal DWI. The feasibility is demonstrated and compared with ssEPI and msEPI in sagittal and axial cervical spine, and sagittal thoracic and lumbar spine.
