Abstract:
A system and method for reducing blurring artifacts in multi-spectral MR imaging near metal include an MRI system having a plurality of gradient coils positioned about a bore of a magnet and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images. A computer is also included and programmed to acquire a plurality of three-dimensional (3D) MR data sets, each 3D MR data set acquired using a central transmit frequency and a central receive frequency set to an offset frequency value that is distinct for each 3D MR data set. The computer is also programmed to reconstruct a subimage for each of the plurality of 3D data sets, apply a de-blurring correction to each of the subimages, and generate a composite image based on the plurality of 3D MR data sets.
