1. An apparatus, comprising:
a diffusion reference image providing unit for providing a diffusion reference magnetic resonance (MR) image of an object using a parallel imaging method,
wherein the diffusion reference image providing unit is configured to provide a folded representation of the diffusion reference MR image of the object,
a fat image determination unit for determining a fat image from the diffusion reference MR image,
wherein the fat image determination unit is configured to determine an unfolded fat image by decomposing fat and water from the folded representation of the diffusion reference MR image, and to determine a folded representation of the decomposed fat components as the fat image,
a diffusion weighted image providing unit for providing a diffusion weighted MR image of the object, and
a fat suppressed image determination unit for determining a fat suppressed diffusion weighted MR image using a combination of the diffusion weighted MR image and the fat image.
