Area of Science:

  • Magnetic Resonance Imaging
  • Neuroimaging
  • Medical Physics

Background:

  • Simultaneous multislice (SMS) Echo Planar Imaging (EPI) accelerates Magnetic Resonance Imaging (MRI) acquisition.
  • Parallel imaging in SMS-EPI reduces acquisition time for diffusion imaging and functional MRI (fMRI).
  • Unaliasimg challenges in closely spaced slices lead to a high g-factor penalty, degrading image quality.

Purpose of the Study:

  • To develop a method for reducing the g-factor penalty in SMS-EPI.
  • To improve the unaliasing of simultaneously acquired slices in EPI.
  • To enable faster, high-resolution MRI acquisitions without compromising image quality.

Main Methods:

  • Introduced interslice image shifts in the phase encoding direction.
  • Induced slice shifts using modulated slice-select gradient blips.
  • Validated the method in spin-echo and gradient-echo EPI at 3 T and 7 T with 32-channel RF coils.

Main Results:

  • The interslice shift method reduced the average g-factor penalty to <1% for 3x slice-accelerated EPI at 3 T (vs. 32% without).
  • Combined 3x slice and 2x inplane acceleration resulted in g-factor penalties of 19% at 3 T and 10% at 7 T (vs. 41% and 23% without).
  • Accelerated diffusion imaging showed no noticeable degradation in fiber orientation uncertainty.

Conclusions:

  • The proposed interslice shift method effectively reduces g-factor penalties in SMS-EPI.
  • This technique enables significantly faster MRI acquisitions with preserved image quality.
  • The method holds potential for accelerating diffusion imaging and other advanced MRI applications.
