A self-navigated Cartesian-based EPTI acquisition (cEPTI) and the corresponding reconstruction algorithm have been developed. High-quality distortion-free diffusion and multi-contrast images can be acquired with the proposed cEPTI.
Figure 5: (a)-(c) The b0 images, MD and FA maps of the same slice as in Fig. 4 from 6 out of 48 echo times.
Figure 3: A comparison of b0 and diffusion images acquired with conventional 4-shot EPI and cEPTI, with a T2 FLAIR image as a distortion-free reference.
