A modified EPI sequence using Phase Angle Tilting (PAT) to correct distortion caused by susceptibility effects was introduced. Using this method, the local distortions were well corrected on both phantom and human. Compared with other correction methods, our method does not cost additional scanning time, and can easily be implemented in EPI sequences.
