Abstract:
A method for magnetic resonance imaging suppresses off-resonance gradient-induced image artifacts due to metal. The method includes performing by a magnetic resonance imaging (MRI) apparatus two multi-spectral imaging (MSI) acquisitions within a field of view of the MRI apparatus, where the two MSI acquisitions have alternating-sign readout gradients. The two MSI acquisitions are then processed and combined by the MRI apparatus using a weighted image combination to produce a final image.

Claim (Index 3):
The method of  claim 1  wherein combining the two MSI acquisitions using a weighted image combination comprises weighting a MSI acquisition m +  with weight w + , weighting a MSI acquisition m \u2212  with weight w \u2212 , where the weights w +  and w \u2212  include effects of both an RF excitation weight w RF  and local gradient weight w G , and where MSI acquisition m +  and MSI acquisition m \u2212  have opposite directions of readout gradients.
