Multi-spectral diffusion-weighted imaging near metal
implants is presented. The presented approach merges
non-CPMG PROPELLER diffusion-weighting imaging
techniques with Multi-Spectral-Imaging methods for metal
artifact reduction. A fundamental demonstration of
multi-spectral non-CPMG diffusion-weighted PROPELLER
spectral bin formation is presented. The presented
methods are then applied in preliminary form to reduce
metal susceptibility artifacts in diffusion-weighted
imaging in phantoms at 3T.
