[Abstract] 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. Techniques like 1D or 2D navigator are widely used to eliminate or alleviate artifacts or ghosts in clinical scanning, while another sequence BLADE or PROPELLER with self navigator is introduced in this work which combines Turbo Spin Echo and radial sampling. This work will firstly introduce the sampling trajectory, motion correction and image reconstruction, and end up with the discussion of scanning time, advantage and disadvantage of BLADE.
