In a method and magnetic resonance MR system for the optimization of angiographic MR images of an examination subject, in which arteries can be presented separately from veins in the angiographic magnetic resonance images, multiple MR overview images are acquired, with at least one imaging parameter being varied in the acquisitions of the MR overview images, at least one optimized imaging parameter is automatically calculated using a quality criterion, and the optimized imaging parameter is provided for the acquisition of the angiographic magnetic resonance images in which arteries can be shown separately from the veins.
