We propose an extra-navigated SENSE-based multi-shot DWI reconstruction algorithm that comprises navigator-based phase and rigid in-plane motion corrections at fast reconstruction times. Furthermore, this approach exploits the low-resolution navigator signal to perform diffusion contrast corrections explicitly within the model. The extra-navigated method is compared in-vivo to a self-navigated reference algorithm. The extra-navigated motion estimation from low-resolution navigator data yields decent reconstructions which perfectly coincide with self-navigated results. Moreover, extra-navigation allows for fast reconstruction at the cost of lower scan efficiency and appears to be more robust for strong motion corruption and high segmentations.
