Data Acquisition for Improved fMRI in areas of Large Magnetic Field Susceptibility

J. Zhuo, V. A. Stenger, F. E. Boada University of Pittsburgh, Pittsburgh, PA, United States Synopsis We demonstrate the use of a reversed (outside in) echo planar imaging (EPI) k-space trajectory for the reduction of susceptibility artifacts in BOLD fMRI. Our results indicate that the proposed technique has artifact reduction properties similar to those of reversed spiral imaging and that it can be easily implemented in clinical scanners as a minor modification of the conventional EPI technique.
