Abstract
A magnetic resonance (MR) imaging technique enables parallel imaging in combination with fat suppression at an increased image quality, notably in combination with EPI. The method includes acquiring reference MR signal data from the object in a pre-scan and acquiring imaging MR signal data from the object in parallel via one or more receiving coils having different spatial sensitivity profiles. The MR signal data are acquired with sub-sampling of k-space and with spectral fat suppression and an MR image is reconstructed from the imaging MR signal data. Sub-sampling artefacts are eliminated using sensitivity maps indicating the spatial sensitivity profiles of the two or more RF receiving coils. A Bmap is derived from the reference MR signal data and the spatial dependence of the effectivity of the spectral fat suppression is determined using the Bo map. In the image reconstruction step, signal contributions from water and fat are separated using regularisation taking the spatial dependence of the effectivity of the spectral fat suppression into account.
