Figure 4: Exemplary results from diffusion-weighted EPI (DWI-EPI with b = 600 s/ ) acquired in mice (in vivo). The conventional EPI (a) shows strong distortions and an “inflated” brain. The corresponding corrected image (b) shows a clearly improved representation of the brain area. The nondistorted image (c) and the PSM (d) are given in the lower row. Note that an artifact in the distortion corrected image in the area without PSM information. However, the artifact is outside the brain area and does not influence other structures.
