Although PROPELLER QBI was demonstrated to reduce scan time and susceptibility distortions while resolving fiber crossings, the residual phase errors in blade DWIs will cause blurring effects in reconstructed image. The purpose of this study was to conduct distortion correction by using image registration in PROPELLER EPI reconstruction, so as to further reduce susceptibility distortions in PROPELLER QBI.
