Purpose:The motion of patients induces obvious artifacts or ghosts in phase encoding direction during MR scanning.Artifacts or ghosts are generally considered as the result of different position of tissue between shots due to motion.Periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER)sequence with motion correction is introduced in this work which combines Turbo Spin Echo and radial sampling.The purpose of this study was to evaluate the effectiveness of PROPELLER MRI compared with conventional T2-weighted fast spin-echo (cFSE)MRI for reducing artifacts and improving image quality in the female pelvis at 3.0 Tesla.
