The sensitivity of diffusion imaging to motion combined with this increased scan time creates a need for a motion correction strategy, especially with uncooperative patients such as children. Here in this work, we demonstrated that the information from the phase encoding correction lines acquired with an EPI acquisition can be used to detect motion in real time, and can be used to improve the quality of long diffusion scan when there is substantial motion during the scan.
