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.
