Multi-shot interleaved EPI (iEPI) and readout segmented EPI (RS-EPI) are two alternative strategies for high resolution diffusion imaging. This study made a comparison of the two methods in different aspects. Our comparison showed that the iEPI had the advantage of largely reducing the geometric distortion. Both RS-EPI and iEPI could achieve high resolution diffusion tensor imaging.
