A method for contrast-agent-free non-triggered angiographic imaging in magnetic resonance tomography that includes the steps of (S1) 2D or 3D measurement of a bodily region having a flow of blood, using a flow-insensitive SSFP sequence, (S2) measurement of the same bodily region using a flow-sensitive SSFP sequence, (S3) registration of the measurement results obtained in steps S1 and S2 to one another, (S4) unweighted or self-weighted subtraction of the registered measurement result obtained in step S2 from the registered measurement result obtained in step S1, (S5) execution of a 2D or 3D image correction of the image obtained in step S4 by removing image distortions caused by gradient field inhomogeneities and/or magnetic basic field inhomogeneities, and (S6) representation of the angiogram obtained in step S5 in the form of an MIP or segmented 2D or 3D vessel tree representation.
