Improved presentation of brachial plexus at 3T using diffusion-weighted imaging with multiple interleaves in the phase-encode direction

Diffusion weighted imaging for brachial plexus can provide useful information for clinical applications. However, clinical DWI usually employs single-shot EPI for signal acquisition, which suffers from image distortion or signal loss especially in the imaging in the head-neck regions due to the spatial variation in B0 field. This work demonstrated the application of a multi-interleave DWI sequence that achieves quality brachial plexus imaging with a resolution of 1.9x1.9 mm² at 3T system.
