Abstract

Computer-implemented method for determining magnetic resonance images (37) showing different contrasts in an examination, wherein magnetic resonance data for all magnetic resonance images (37) are acquired using the same acquisition technique and the magnetic resonance images (37) are reconstructed from their magnetic resonance data sets using at least one reconstruction algorithm, wherein reconstruction comprises at least one denoising step (S2b), wherein- after acquisition of the magnetic resonance data, at least one noise strength measure (38) is determined for the magnetic resonance data sets for each contrast, and- denoising strengths for the denoising step (S2b) are chosen individually for each contrast depending on the respective at least one noise strength measure (38).
